Plz i really need help.

So i've been depressed for a

while now (maybe like 5-6months)

And 2 weeks ago when i was about to eat food but i just sat there, i didn't feel like eating at all (i always eat a "normal" amount of food). Like i was very hungry but at the same time i wasn't. I tried to eat, but could only eat a little piece of chicken.

3 days ago i started to eat a little more again but i still "can't" eat as "much" at the time as i used to before this happened because i feel like my stomach probably would get weird or something.

Can anyone relate to this?

& is this because i'm depressed or is it something else?
