Don't get baptized just because your parents are pressuring you to do that. You might even ask them, "Do you want me to get baptized because you are pressuring me, or do you want me to get baptized because I love Jehovah?" On second thought, maybe that's not such a good idea 'cause then they'll want to know why you don't love Jehovah enough to get baptized.
I agree with Stephanus about seeing if your grandmother could let you stay with her while you get things sorted out. It would give you breathing space to think and plan. Also, when you are 18 you can open your own bank account (most banks have a policy against allowing those under 17 to have their own account, a parent must sign on the account until they are 18.) Even if your parents won't give you the money you have earned, at least you will be able to keep whatever you earn after you turn 18.
Good luck. And remember "Suicide is a permanent solution to a temporary problem."
