I have been thinking about the doctor telling me I need to gain weight.

Maybe it is true. It may be a better hypothesis than high progesterone.

I am quite skinny (too skinny, probably). I don't really have any fat. I looked at a few pictures of me from about 3 or 4 years ago, and I definitely had fat on my face, which I have none of now.

It could possibly improve my appearance to gain some weight. It would make my cheeks less sunken.

I guess, if I work out, I could eat more, and gain some fat and muscle.

Gaining some fat would probably be good for my skin quality as well as general aches and pains, so I guess I can give it a try.

I am never hungry, though. That is the problem. I guess I just need to eat, regardless. That sounds like it could be a level in Dante's hell
