Does it really get better? Life no longer feels worth it :'( ?

I'm at my wits end. I have depression, insomnia, anxiety, aspergers, OCD, and trichotillomania. I'm in counseling and I'm on meds but gosh... Life doesn't seem worth it. I don't know what I want to live for. I'm starting high school and I'm scared sh-tless. Does it get better? I have no friends and hate life. Is there anyone out there? It feels so lonely in this world.
