angry all the time

i'm pissed off all the time. i have generally bad interactions with my family, my brother treats me real bad, he calls me names, sais to me get out of the house, no one wants you here, they all want me out of the house, they don't like me cause i raise my voice at them and curse but i don't do this for no reason, they always provoke it.
i'm so unhappy i don't want to live anymore, i feel like crying all the time, they just don't understand its not my fault, i have several disorders and they don't even recognize this. my brother always sais " u don't have anything, you're not sick, you're just an acctress...."
this makes me so freakin mad, i don't know what i can do, and i just can't talk in a regular voice, its like physically imposible for me, most of the time my voice is very high or i'm shouting.
i have suffered from major depression, OCD, i've been labled with having a emotionally unstable personality disorder, cause i get angry a lot....i don't even know if i have that or not. but i am sure my anger is justifiable, since i'm always provoked, i mean i'm a human being for gods sake, i have feelings too..... i have needs and wants like everyone else, but i get no sympothy, no understanding, no kindness....i feel like i hate everyone and they dislike me too.
my life style or behaviour earns me no respect from them, which i can understand....also so many people are living under one roof, and i don't get along with any of them. plus i have a baby neice living with us, which makes the situation much worst, cause they don't want me raising my voice with her in the house and all, and i'm like, but you're the freakin cause.

Hi, Maya, (((( hugs ))))

People will always provoke, this way or another. What I learned is a sort of " positive avoidance", that is if you can't reach out to the people who provoke your anger and they don't acknowledge or respect your requests ( which is commonly the root of anger ), you may then try to find support and comfort on the other side, e.g. a friend you can talk to, a boyfriend, some hobby groups, etc. This way you will find a place on the other side where you will be comforted and thus their provocations won't have the power to get to you anymore. Because you'll know you are loved elsewhere ( never mind where and how, the sense of being loved is important, which can even be achieved by auto-suggestive techniques, i.e. starting to love and be proud of yourself).

- do you personally, intimately believe they are better than you ( self-esteem issue ) ?
- do you think you didn't do enough for yourself ( not by shouting, but by more refine techniques) to fight for your own rights in that house ? see, it's like a state. As a citizen ( house mate ), you must for your own rights all the time, and no one else can do it for you. However, it's done with carefully planned strategies, not shouting. For example, every time they verbally abuse you for no reason, just do it back to them, or refuse to help them with housework, or any other sort of punishment, but don't shout. It will punish them better than shouting.
That's one option. Hope it helps.
