I hit myself when i am angry. i sometimes bruise myself. how do i stop?

[SorrowBlinded]

i've hit myself when i am angry since i was a child. sometimes i would cut my arms, legs, and thighs. i have been through countless therapist and nothing changes it. i never feel it as i'm doing it. so i hit harder till i feel the pain. it normally happens when my husband and i fight. he'll chase me through our apartment and taunt me about it. he makes fun of me and says i'm crazy then threatens to take my child from me which makes me do it more. i fear that if i don't stop i'll lose them both. i don't want that. i love my husband but when i tell him to leave me alone during an arguement it only makes it worse. i quit doing this for a yr. he was deployed for 7mo. and once he got back nothing has been the same. i feel lost and confused because he is the reason i came to love myself but now he says things to me that make me hate myself. when we argue he starts to yell and say hurtful things so i try to leave the room and he follows me i plead with him to just stop and leave me be but he just keeps yelling and saying how awful i am, i scream for him to stop but he won't and thats when i begin to hit my legs, chest, or face and repeat leave me alone. after it's all done he tells me he is going to have me put away because it hurts him to see me like that. i want to stop. i want to show my child how to handle anger in a healthy way. what the hell is wrong with me? why am i so awful? why do i hurt myself till i bleed or bruise?
