Can't get your spells to work? Try learning the basics more. It takes time. It really does. If you want to be successful you have to have a solid foundation. Spells are not just chanting or saying some words, there is way more to it than that. And that is what you need to learn.
I know your situation is bad, but isn't life bad for everyone at some point? Besides, magick cannot fix everything. Report your parents to someone if they are abusive to you. They will be able to place you with your grandma if you wish, since they take the child's best interest at heart, if your grandma is able to take care of you.
Never, ever pay money to have someone cast a spell for you. You don't know if they cast it or not and just take your money. Never, ever give out personal information like that to someone you do not know. I don't mean to be rude, but do not seem so desperate as to do that. It would come back to you and possibly not in a good way.
No one on here really likes to cast spells for people, especially over the internet and if they do not know you personally.
The only help/advice I can give you is to learn the basics. That will help get you started.
And think about this the next time you want to make a thread. This is the second time I have posted help/advice to you. If you keep posting like this, you could get reported. I know you want help, but it takes time, and the people on this site are not here to help you through emotional/family problems. We are here to help you with magic. Which is what we have done.
