Lately i've been feeling really down and I don't even know why! I'ts been making me really irritable around my family, to the point where I get really mad at my mum. I don't know what to do. It takes me ages to go to sleep at night, even when I'm tired, because i'm just so sad, and can't stop thinking about things and how much of an idiot I am etc. Sometimes I just feel like crying.
Could I have depresssion?
