What happened to my appetite?

I'm a 15 year old girl who works out and takes care of herself mentally and physically (at least i try to). But recently when im about to eat, I get an ick, even if it's something I usually like. I sort of force myself to eat to make sure I have energy to exist, but I don't find myself to enjoy it as much. I have had a minor eating disorder in the past, but im pretty sure I've fixed my mindset now. Any advice or information would be appreciated, thank you for reading.

(I know it's weird to post it here but every other community kept deleting my post smh)
