I NEED to run away... somone.. anyone... plz help me...?

kso, ik this might sound, well, dumb. BUt its something i NEED to do. i need to leave my house, before i go crazy! my reason? well my mom is crazy, and when i mean crazy, i legit mean crazy. She doesn't have a job and she goes around like yelling and screaming at people about the random est things, my whole family has told her to go and get help but she refuses. Every now and then shell start yelling about god knows what and Thur things scream threaten and in about an hr and a half, 3hr tops, shell calm down and act as if nothing happened. ik that sounds weird, but its the truth. Anyways, when she does that kind of stuff ill just go to my dads house ( he live right there so it takes about 5 min) but when i get there ill ex plane why im there and hell get mad cuz the thinks my mom is stressing me and he has friends that have kids that have died because of stress and stuff like that so he gets worried and hell call my mom and they'll start yelling at each-other threaten each other etc. Me being 13 don't know what to do but cry... usually kids like me talk to there trusted friends about this kind of stuff so its not on there mind 2.4.7. But for some reason, i think that's a bad idea and most of my trusted Friends tell their parnetens everything and i don't want anyone else finding out about my " problem" so you can only imagine how stressful this is, counting my stress from school. i mean im not a loner or anything, im actually pretty popular, but my grades arnt the best. now, plz don't tell me i shouldn't do this cuz i already know i shouldn't do it, and its not a matter of what i should and shouldn't do its a matter of what i need to do. ive put up with my family for a while now and i don't think i can do it any more, i just need to get away from here before it gets to the point were i become suicidal. ik that's a bit drastic i would NEVER do it, EVER, but its crossed my mind and im afraid one day ill get so mad...a dn it might be to late, like i said before, i don't want a lecture, i want to know how to be ready....
