I think I'm depressed and want to medically confirm it. I either eat a lot or don't eat at all. I cry sometimes suddenly even at the smallest things. I remember things and I cry. I start self doubting and then just start losing concentration on everything. Since I lost the concentration, I end up with bad outputs in my work which leads to my manager talking to me. If I get one slight downward emotion, by the end of the day, I'm curled up in my bed thinking about how life has no meaning.
