Depression. What should i do.

My husband is addicted with alcohol from last 1.5 years. Before he drunk every day but now he recovered himself. But he couldn't stay in sense when he started. He usued slung and hit me for any reason that time. He behaved very rudely in that condition. But he couldn't remember anything when he is in sense. He feels sorry that time. But i am becoming mentally sick and physically too due to his behavior. I can't forget anything when he be in sense. I can't sleep for a day also. My head pains so much. Feeling so so upset and depressed always. I feel scare every time if he again start drink and behave me again like this. Only think about all and for that i fight with him for some issues and try to commit suicide some times.what should i do. How could i recover
