Don't have an appetite...

I've been trying to eat more to gain weight but recently I have not been able to eat.  I'm just not that hungry.  Help?  What's the matter with me?

Ive been having the same problem. Right now im just trying to eat more even when i dont particularly feel like eating. You should try to eat every 2.5 to 3 hours even if it means just a snack. Im about to have a peanut butter sandwich even though i know its gonna be painful to swallow. I think the more you eat your appetite may return.
