How do i deal with this crap?

well my 2 brothers just came to stay with my family for the summer, i never met these brothers ( that another story). So they are like strangers, and this is just messing my summer up. I mean i don’t got my personal space any more, cause they sleeping in my room! so i can’t watch tv, can barly get on MY computer and, i can barly play my 360. every time i try to relax in there they always mess it up, it putting me in a bad mood. Which making me take my anger out on other peoples didn’t do nothing wrong, i don’t got no place to even have some private time on the phone with my girlfriend. Every time i try to talk to my mom about this she start acting so childish! Like oh well ill move out and they can have my room bah bah bah! my girlfriend said i can move in with her, and am thinking about talking to my mom about it, cause ill go insane living in this house for the WHOLE SUMMER! these fools havn’t even been here a full day yet and am already annoy, i just don’t know what to do, mom won’t listen and them fools probably will have a smart comment to say back to me if i say something. So i don’t want to try none of that, I’m really considering moving into my girlfriend mom house. She said it rent free to ( and her mom said it is ok) so the deal can’t get much better then that. but help please? cause i can’t take it no more,

P.S there no way my brothers can move out, cause they live in a whole different state. So they pretty much stuck here still the end of the summer -.-!!!!!
