what do i do?

i feel so strange today. night before last i reached my breaking point and blacked out. my husband is a raging alcoholic and i drink ocasionaly. well i have endured 10 years of mental and emotional abuse because of this mans devil tounge. i will admit that i had a buzz but i disnt drink too much because i have bronchitis. i took a dose of nyquil and a few shots to help me sleep over this awful cough.
well he started in on me....i wont go into the specifics of the actual conversation but i really hit my breaking point. i beat the snot out of him. granted he deserved it but that dont make it right. i am 5'9 170 and he is 6'3 200 so that should let you know the state of inebriation he was in. normally i cant even get past him if he dosent want me to. i honestly dont remember much of this. i remember him taking the clock off the wall and putting it in my face and i took it and threw it at him but that is about all.
i really dont feel bad about it because he has pushed me around long enough. but i had been cycling rapidly most of the past week and i just think he pushed me too far. i know really know what i need from you guys i just needed to vent.
