Hey everyone, I'm a 15 year old girl with what I think is some pretty severe depression problems... my dad is horrible, and causes most of my pain (both physically and mentally). I've tried to get help but nothing helps and I think I need to see a psychiatrist but I have absolutely no money to pay for it :( can somebody help me?

The best help doesn't come from psychiatrists, who merely prescribe medications and ask how you are for about 5 minutes, but from good talk therapy. In the US a therapist does have to be a licensed psychologist or social worker, but the cheapest (and often free) version of that is group therapy. A school nurse or guidance counselor is supposed to be able to at least steer you in the right direction. Look in your local paper for a Support Groups column. In a pinch you could even go to an al anon or al ateen meeting for families of alcoholics.
Meanwhile, tell us how your father is physically hurting you. Although yelling and any kind of verbal abuse isn't against the law, physical violence is. You should report it, either directly to the police or through an adult you trust.
In fact, tell us all about your depression in general. Writing about it here may help.

Agreed with the above advice. Talk to your school counselor, that's what they are there for!
And keep your chin up, you only have to deal with your Dad for 3 more years, then you
Can move AWAY. :)

Talk to someone at school, or report physical abuse to police, they will get you help.
