White people problems. (Pretty pathetic when coming from a white person). Oh, you can't afford to go out to diner, or to pay for a gym membership, or art lessons, or piano lessons? Boo-hoo! It's called LIFE. Most people don't get those things and they manage to survive. Yeah, sorry to hear about the divorce and all, but come ON. Stop trying to get people to feel sorry for you and put yourself out there for you talents rather than for pity. My parents split up and I got over it. If they can't work together to make life comfortable for their kids than they should never have had kids in the first place. I'm sick of it being a standard that divorces have to be expensive. They DON'T. When they get to that point it's usually because one or both sides are being childish and not taking responsibility. This is a big part of why I don't believe in marriage to begin with. In any case, you need to stop trying to get people to feel sorry for you. Things sound a little tough for you, but there are people literally STARVING to death in this world. Your problems are not nearly as bad as you think they are. If you really are fifteen, you are already on your way to being a very good manipulator (although I kind of have a feeling you are not actually fifteen based on some of the things you said in your post). Grow up.
"(I may talk bad about him, but I love him very much. He's just lazy and makes bad choices... I may bad-talk him sometimes, but he's still my father. I love him very much.)"
You sound like a better daughter then he deserves. I had a lazy parasite step-father. He was my step-father for pretty much my entire childhood (at least entire childhood I can remember). Forgiveness is something beyond my capabilities.
