In my case, I must separate two stages.
The first: I weighed between 450 and 500 pounds, and that's when it all started.
I had gained weight naturally, and the idea of ​​being even bigger was tempting, but I can't say I just wanted to gain weight no matter what.
I didn't want to remain immobile, and some health issues frightened me. I just wanted to gain a little more weight, to the point where things became difficult.
It was a fun and humorous stage, where I truly enjoyed being obese. I even went from wearing baggy clothes to hide my fat to wearing tight-fitting clothes without any shame. It was also then that I needed to use two chairs to accommodate my butt, and the whole experience was very pleasant.
The second stage: At this point, I was already trying to justify my immobility and debating what to do.
I never stopped eating and gaining weight. I was using a bariatric wheelchair and a walker.
My life was reduced to the immediate vicinity of my home, and I was lucky enough to walk a couple of steps before collapsing gasping for air.
If I'm being truly honest, I decided to enjoy food with the excuse of gaining weight beyond immobility.
I had a massive food addiction that I never wanted to leave behind, and I'm talking about eating enough for five adults at every meal.
I chose to keep playing the game. My husband would fatten me up and take care of me while I dedicated myself to eating and gaining weight.
At 900 pounds, I was already a useless mass of flesh resting in a bed. I couldn't sit up or turn over, and I had severe fluid retention that made it impossible to control my blood pressure. Then I suffered a spike in blood pressure, which I recovered from without consequences.
Immediately, the game was over, and my husband restricted my calorie intake. I was crying out loud, begging for them to please feed me.

Immobility requires significant expenses to access comforts, in addition to requiring permanent assistance. In my case, we had to hire a nurse.
The bariatric lift is essential, but when I reached 900 lbs, it was torture to be suspended in the air with it.
Too much weight, and the bed compressed my entire body, causing me great pain.
They helped me gain weight, and I enjoyed eating everything I could swallow at each meal. But at my heaviest weight, I was completely useless and couldn't turn over in bed without assistance; getting out of bed with the lift was impossible.
The fluid retention was extreme, and they couldn't control my blood pressure; my legs hurt a lot.
I was extremely limited by my weight, and all the comforts I had in my room became useless. I was truly suffering from my weight.
Still, no one stopped feeding me, and I didn't stop demanding food either. Luckily, I collapsed due to my high blood pressure, and my husband said enough was enough.
I lost weight and am on a "controlled" calorie diet. It's not a diet, and sometimes they let me overeat, but my body reached its limit there.
Today I weigh 700 pounds, and I remember that at that weight I could walk, but I'm still bedridden.
Being in a bed with no comforts was horrible, and even more so having poor hygiene because of my body size.

You decided to gain weight, and the reaction of your family and friends shouldn't affect you.
I'm warning you that no one is going to congratulate you or react pleasantly.
I don't know what you mean by extremely obese, but if we're talking about being over 600 lbs, you're not going to go unnoticed anywhere.
At that size, you'll be exposed to uncomfortable situations all the time, which will generate reactions from onlookers.
If you're worried about people's reactions, just don't do this. Everyone will remind you that you're incredibly fat, that you should lose weight and stop eating. Besides, the fact of being extremely obese and being observed eating or sitting already generates reactions. Not to mention if you appear in public eating and sitting in a wheelchair.
When I could walk, I used special public transportation, and there's a double seat designated for obese people. When you get on and people have to give up that spot for you, they don't look kindly on you. To people, you're a lazy, unproductive fatso who takes advantage of the system, and on top of that, the system itself encourages you to continue with your lifestyle.
You don't need to prepare yourself unless you're not confident in what you're doing. I've always taken negative comments as a compliment.

I'm extremely obese and bedridden. That belly area, along with the crotch, is very tricky. It's prone to injury or rashes, and I can't reach those areas of my body with my hands, and I don't have a visual inspection.
It's best to clean frequently and keep that fat fold dry and ventilated.
Cleaning, drying, applying talcum powder, and, if possible, lifting the fold and exposing it to a fan helps a lot to prevent fungus and rashes.
Moisturizers aren't much help.
Summer is when the skin in that area of ​​my body is regularly checked. It's difficult to keep it dry because it sweats a lot.

Being bedridden due to an illness isn't the same as being bedridden due to obesity.
In a sudden accident, you have to leave your life behind.
When it's due to obesity, it doesn't mean something sudden. You even gradually lose the ability to walk, and one day you're lying in bed.
Also, in my case, I was initially unable to get out of bed on my own, and I was still able to take a few steps. Then I would collapse on the bed gasping for air, but I could take a few steps.

The best plan is to find someone to take care of you.
Not working is the least of the problems for someone with that level of obesity. Even the fact that you won't be leaving your house is the least of the problems.

I'm in that fight. But I can't exercise, and when the stress becomes too much, my nurse helps me get food.

Finding clothes is impossible.
I've been bedridden for a year, and I stopped wearing clothes.
There are no sizes for people my size. Special sizes are misleading, and I often bought pants that didn't fit properly.
It all came down to wearing 16XL leggings that were sometimes tight and ripped.
T-shirts were either too short and tight, or too long and also tight.
I could never find my size in T-shirts.
Unfortunately, I had to buy clothes blindly, hoping something would fit.
The downside to tight clothing is that sleeves, whether pants or T-shirts, if they're tight, cut off circulation.
The upside of being bedridden is that I no longer have to worry about clothes, much less shoes.

When it comes to everyday life, anyone would be exhausted. It is not easy to take care of a person who needs assistance 24/7.

An obese and immobile person thinks more about what he or she is going to eat than about what could happen in the event of a natural disaster.
In my condition, getting out of bed, leaving the house and then transporting myself is a challenge that requires logistics and the joint work of several people. I even need medical transport designed for someone of my size and, if I am lucky, there is a unit miles away. In the event of a heart attack, I only receive assistance at home and, if surgery is necessary, I am condemned to die.
Natural disasters are minor things and if one were to happen, they cannot do anything to get me out of the house. I do not believe that in an emergency they would allocate vehicles and personnel to get a fat, immobile person out of her house.
