stop getting mad so easily

I moved from orlando to new Jersey and I never really adjusted to it, the people in this town are more obnoxious than any group of people I have ever met. They are immature and concentrate on really petty things and are all basically conformed. I feel like I’m loosing myself because I’m not happy anymore and it’s going to be my third year here. I’ve accomplished more academic goals here, but my personality is dimming and I feel like I’m acting snobby and dressing like them just because it’s easier. I hateee who I’m becomming because I’m mad all the time and it’s ruining my relationship with my boyfriend because i take things out on him, and it’s hard enough we have a long distance relationship but I see him every chance I get like summer, and he’s visiting me on christmas. I think it’s easier giving in and being mad at the place I’m in than trying to be happy about everything like I used to be, regardless of how bad things got. How do i stop thissss

My sister is in town for the holiday, I have always gotten in an agruement or annoyed with her easily. She can be real immature and stupid at times. I am four years younger than her, and she thinks it is funny at times when she does things to me but I want to punch her. Not literally, but you know what I mean.
When she came here, I offered to share my room. As people know me, I like to keep my things neat and in my orderly fashion. My sister trashed my bedroom, and it made me real annoyed, as like I offered my room to her, she doesn’t have a bedroom here. I am being nice. So yesterday I asked her to pick it up, she didn’t. I took it into my own hands, I kicked her out. I couldn’t handle it.
Today she put her clothes on the bathroom floor, I freaked. I went downstairs to my mom, and explained then got mad. I get mad at my mom for not doing anything about it.. they make me do it, but my sister doesnt listen to me. Gah! So I got madder and then swore at my mom, called her a jacka%% by accident. In my family, swearing is not the best thing we want to do. It’s not right, we dont approve it. But I get so mad that it happens. I feel awful about calling her that, she didn’t deserve it. At all. I do feel bad. I get really emotional. I make myself cry alot, sometimes there is no reason for crying because it doesnt make sense if I do that. I am not depressed? Maybe I am. I think I am alittle bit. I just need help on trying to be less mad, and less dramatic. Does anyone know? Email me, all your thoughts prob will help.

Finally I don’t get as mad as often as I did…I breathe before I do something!

Idk?...I need to think before I do stuff…in some things I totally gotten better but others…I REALLY need to work on it…I just need to breath!

I’m not getting to mad at anyone as much as I did…I still need to breath once in a while….but can do it. Maybe if I get a new enviroment or think about getting mad.

I really need to stop getting at my mom so easily….I get along with every else…I mean me and my mom fight about stupid stuff…like cleaning and stuff….
