SkinnyD:
I can't deal with salty stuff like the packaged ramen, or a lot of prepackaged/processed food. Remember that diet can affect depression tremendously too, gut health and nutrition play a major role in brain chemistry. If you put together a better diet with exercise, you may find that it helps alleviate the depression more. I think that's part of the reason gaining helps me as well, I realized that before I just wasn't eating enough and not getting enough nutrition. I thought I was, until I started tracking my food to help with gaining and saw what a difference it was.
I definitely recommend those Orgain protein shakes. I've been looking through the freezer at each supermarket I go to looking for frozen meals I can leave in the freezer at work for a quick economical lunch. Some of the things I've found on the healthier side still have a decent number of calories and taste pretty good, and don't leave me feeling sick from artificial crap and salt. You would be surprised how good and high in calories some of the vegan frozen dishes or meals are.
This is a slight tangent because it doesn't involve OP specifically but rather the feedist community as a whole.
A lot of feedists will eat like absolute shit to get fat and wonder why they feel horrible. There's a fear that if they eat healthy, they'll lose weight. I've run into people who avoid veggies or only eat fast food because of this.
These people are some of the most miserable, mentally unstable people I've seen. There's a reason why we were told growing up that junk food is a sometimes food - it's not just about staying slim.
I'm not going to say that a good diet fixes depression, but it certainly can help.
Back on topic. To OP, SkinnyD is right. It's good to get something nutritious you won't struggle to eat. At the same time, however, sometimes eating something is better than eating nothing. Sometimes life is hard, and the best you can do is bologna and a bag of chips. It's not the best, but it is better than nothing.
