I have been suffering from episodes of extreme unhappiness for around a year and a half. These episodes often happen when I'm alone. During them, I'm overwhelmed with a feeling that I'm completely worthless, I'll fail at life, I'm ugly, stupid, etc. Nothing seems to cheer me up, the future seems like a horrible place, I can't move or distract myself because I'm crying so hard. Then I feel even more worthless because I wonder why I'm depressed when my life isn't bad, I feel melodramatic. My life is average I do averagely well in school, I feel ugly but I know I look average, I think all the averageness just makes it worse, like I have no place, am ridiculously unimportant. I feel like crap. And then, after about an hour I'm fine. I feel nit bit apathetic and still can't concentrate, but otherwise ok. Until the next day. And repeat everyday. I dismiss it when the episodes aren't in progress and when they are i can't do anything. But all the other hours of the day, I'm relatively ok. What should I do?
