Uh....Help?Advice?Apologetic complaints?

Well you see, I'm in a bit of a pickle. I keep dying my hair, right, so my dad comes in my room to see my new 'do, which of course is pretty much the same, owing to the fact that the Sally's beauty istant is a bit stupid. So he comes in my room, and the whole deal ends up with him yelling an threatening to slap me across the face (which he almost did, with gusto). You see, my dad is generally a very very quiet and gentle soul, being a triple gemini. So I'm a bit confused. Add to that my friends are all....shunning me right now, and my mum isn't really speaking to me either. Oh, and by the way, I'm almost broke, don't have a boyfriend, don't go to school, and have no perspective lovers. And I'm underweight. So. There's the story of my life. Any help on what I can possibly do to help myself?
