As I thought everything was going to be alright but than just wasn't alright. Well, I guess things are just upside down .

Well, if it isn't school than home.
At school my friends be talking shit about each other, and I will be stuck in the middle listening.
And at home well, let just say that thing aren't quiet "HOME" Grandparents is always yelling at me, and I'm sick and tired of IT! They be complainning to my mom. And I will be complainning to my mom. My mom say that she is going insane, and she will suicide just to make us get along. I don't want her to. I don't know what to do.

im in a similar situation [the friends part]. my friends used to accuse me of talking behind their backs too, so now when my friends start doing that i just tell them that i dont want to hear it and they stop.
about your family... do you know why your grandparents are yelling at you? negotiate with your grandparents so your mom will hopefully not resort to such drastic measures.

for your friends, just listen to them don't try and get involve that'll just make things worst for you.
for your family, you know how grandparents are, talk to your mom about it, see what she can do to make your grandparents stop yelling

^ Agree. Stay out of it.. or pretty soon you'll be taking sides too.

As for your family.. would your mom really commit suicide because of the argument between you and your grandparents? Like, truthfully..? My mom also says that sometimes when she's depressed.. but she never means it.

if your friends are pissing you off, than just leave them alon for a while. there is nothing wrong with not being with your friends for more than a day. and at home, just do whatever your grands say. i know that it is really bard but just do it. it would just be the better thing to do so that maybe they will get the hell over themselves.

For the friends part, just put up with it. It's bad to confront them =\ it will evently stop. Cause then they can't prove you talked bad about anyone of them.
For family, I guess treat you grandparent like royalty.
