I can't even be "happy", i do not know the last time I was feeling happy. For a few hours I will feel not depressed, may a few days(but that is rare).
It sucks, I think one of teachers notived, because I heard them talking to a co-teacher that I looked sad. I actualy wouldn't mind telling him,but I wish someone would ask how I feel, then depending on the persom, i would tell them.
