I'm new here, though I'm an old lurker. So hi

It's all a bit much for me at the moment. I'm at university but I have stopped working, I'm so worried I'm going to mess up my degree, and I got a poor result on my assignment today which made me feel bad. I can't concentrate on anything. I started anti-depressants but they haven't done a lot yet. I see a therapist and he is trying to work me out some long-term therapy. He said he'd mail me about it this week, but he hasn't. I feel let down. And then I feel silly about wanting him to mail me so badly. I think about him all the time, it makes me so sad that he doesn't love me. I hurt myself sometimes.
I don't know what I'm asking really, I'm just overwhelmed. I don't even know where to begin fixing this.
