I wouldn't get too hung up on bone structure. I'm quite lightly built in my limbs - thin ankles, knees, wrists etc. - but I have still been able to put on a decent amount of muscle through regular weight training. It probably doesn't help, but it's not an insurmountable issue either.

LOL. If I ate "normally" I'd be so skinny I'd be ashamed to go out in public.
If you want to get bigger, your body needs the right nutrients. If you only eat crap then it will struggle. I'm guessing that you don't want to just put fat around your torso, but get bigger overall. On your limbs particularly, this involves putting on a bit of muscle. If you do this, you'll be healthier, shapelier (I appreciate this is a bit subjective) and will have a higher quality of life by being able to move better. If you put on 50lbs of fat onto a small frame it will slow you down considerably.
To do this you need to eat well and exercise. Just adjust the quantity of food up a bit!
