I'd go and see a psychiatrist get medication and lay off the booze.

I agree with Harmony. You need to seek professional help. Self medicating with alcohol is not going to help. Self harm is a symptom of much deeper issues. You are in pain and you need to see a therapist to help you sort out these issues.

Drinking that often may lead to life long withdrawal issues whenever you have a drink like I've got, so slow that down. Checking with your family doctor for anti-depressants is probably one of the best routes, maybe take time off work while you try them out. They can definately change your life for the better

It sounds like you are tired of feeling like this and doing the things that you are doing. You also sound like you are willing to admit that there may be a problem with you. You suffer with the disease of addiction and it will kill you if you don't seek help. There is no shame in asking for help. A start would be to look into addiction treatment centers in your area. You are suffering spiritually and psychologically. The cutting most certainly won't improve until you have sobered up. I'm not talking about a day without alcohol or drugs, I am talking about a longer period of abstinence. You can do this. If there is not a drug or alcohol treatment center in the area, try walking into an Alcoholics Anonymous or Narcotic Anonymous meeting. There are people there that have been through what you have and they are waiting to help you. There is life after this and you will wonder why you stayed in your problem so long when you start to find your way out of it. Hope this helps!
