My head aches constantly, I'm always tired and falling asleep and I hear th!

I've had it rough for the past few months. I've been seeing my psychologist twice now. He said I was university material and I'm only 13years old. I told him about my headaches, on a scale of 1-10 they would be around 9, I think they'll pass and he asked me how long have I had these headaches and I said I couldn't remember, a year, maybe two? My sleeping is perfect, I get 7-9 hours of sleep every night but I fall asleep during class and I even passed out randomly because of exhaustion. Is there something wrong with me? When I told the psychologist he frowned and became very serious and aware. He also knows that I hear four voices in my head, constantly arguing and telling me to do stuff, making me indecisive about everything. I also have to mention I get this ringing in the back of my head, like a sharp bell. I'm exhausted and I think I'm going to pass out again, only been three hours since I've slept. my next appointment is in two weeks and I'm not sure if I'll make it that long, so many questions and I get into a dark depression again, I cut myself and I bleed quite a bit, I was forced into smoking a few times, sexually abused, hit, slapped, punched.

I don't know if this is something serious he saw or if it is just part of depression or anxiety? But I started hearing things when I was five years old, the headaches in grade 4 I think and the tiredness since grade 4 as well.

Please, someone help me...
