my mom doesn't want me,i don't want to live with my dad,or grandma what can i do or go??

How old are you? I moved out when I was 17 but I moved in with my friend and her mom. Otherwise your just gonna have to stick it out. That's that price you pay for being young. I suggest you go to the library and get some self-help books in dealing with parents. They're yours forever so I suggest you start learning how to like and "live" with them. It sure would make the next few years a lot easier. Just try it. Know ever thinks of trying to get along. Just how to get out. That's probably why the divorce rate is so high: people just wanna leave instead of trying to make it work.
Go to the library or a book store and find some books on living with your parents.

First of all .... plz get the thought of running or killing out of ur head.
Secondly, are u sure ur mom does not want u?....if u r then why dont u give ur dad a chance? or ur grandma? ..... i dont know how old u r but u have to put up with this situation for maybe 2-3 more years?...... so wots 3 years in front of the next 50 years of ur life?..... its not much. So think abt ur rest of the life.... plan for it...... study for it ....... and most important - fight for it.

Dont let the disppointments of ur life right now take over ur life to the extent of u thinking such negative thoughts. This situation u r in right now will not b there for next 50 years , right?....so think abt that and brace urself and endure the situation for a few more years - they may seem long but they will end - have faith. In yourself n God. Take care and plz dont do anything rash.
