No appetite

Before I had my daughter, I was feeling depressed around 8 months close to 9 months I was eating but I wasn't eating like I usually would because I guess I wasn't hungry. Now that I'm no longer pregnant, I have no appetite whatsoever and I'm still depressed, honestly like I can't even eat like when I was pregnant or even before I was pregnant. Before I got pregnant, I wasn't eating a lot I guess normal? But now, I can't even eat anything if I try, I take a few bites and I'm literally full. I don't feel hungry at all, I don't know what's wrong with me..
