Alcoholism Support Group
Alcoholism is the continued consumption of alcoholic beverages, even when it is negatively affecting your health, work, relationships and life. If you think alcohol is causing you to lose control, it's time to seek help. Our group is a safe place to vent, check in, get back up if you fall, and reach sobriety.

I'm hoping that you have access to professional mental health care? I'm in the United States, and am currently uninsured. However, my state has public health clinics that charge on a sliding scale. I believe they have some mental health and substance abuse access, but it may be a long wait. If you live elsewhere, I hope it is in the UK since there are several other members of this group that live there and might have thoughts on finding the best professional assistance.
If you do have good insurance, please put it to use. Do some homework and try to find mental health professionals (therapist and psychiatrist) experienced with BOTH addiction and depression, ideally someone that lists "dual diagnosis" as an area of specialty.
Many hospitals have addiction support groups that are geared toward dual diagnosis issues. The right therapist and psychiatrist should be able to help you locate quality resources. AA, SMART Recovery, or some other program of your choice would be a really good idea. You may need multiple strategies, particularly in the beginning.
As many people have pointed out, it is possible for people with depression to stop drinking. If the depression preceded the drinking, it will not be eliminated by sobriety. The good news: eliminating alcohol will, in time, decrease the intensity of depressive episodes. The bad news: the depression may worsen in the beginning, and it will likely be accompanied by a lot of anxiety. Given the extent of your current depression, that worries me. For this reason, I'm wondering if inpatient treatment might be the way to go. Also, most of the suggestions here, mine included, require a degree of taking action. When someone is in a really dark place, sometimes action seems impossible.
Having been hospitalized for suicidal ideation several years back, I have some mixed feelings about the experience. It certainly wasn't all good. At the same time, it was a vacation of sorts, in that pretending I could function or take care of myself was utterly ridiculous and exhausting. Taking a rest from my "acting career" did restore some energy and get me past the worst of the crisis. Inpatient treatment didn't fix me, but it helped me recharge to the degree that I was able exert some effort and make some positive changes after I returned home. Then again, that was just my experience. Therefore, I hesitate to strongly advise checking in somewhere. Think of it more as an option to investigate. Also, anything I've suggested is in the spirit of trying to get you in a better state to work on the alcoholism issue. Your inner demons seem to have you half-convinced that getting sober is hopeless. Inner demons give crappy advice. The role of mental health professionals is to help you give those negative inner voices the middle finger.
Maybe some other folks here will weigh in on the inpatient treatment issue? Curious if anyone has thoughts on IF inpatient treatment is a good move. If yes, what kind? I'm uncertain if something is available specifically for dual diagnosis patients. Rehabs must see their share of other mental health issues, and psych units likely see plenty of addiction. Anyone out there have information on what type of places might be best equipped to deal with both concerns?
I'm wary of someone that seems overly eager, particularly at the first appointment, to prescribe a cocktail of powerful meds at high doses. Excessive enthusiasm about antipsychotics is, in my opinion, an enormous red flag.
Some people may need antipsychotics. For them, the side effects and hazards are worth the benefits. Sadly, a majority of prescriptions written for these drugs are entirely inappropriate. Unless the doctor has evidence that someone has off-the-charts mania or marked psychosis, they have no business giving someone drugs that cause the following: permanent tics, severe diabetes, massive weight gain, sudden cardiac death, atrophy of brain tissue, and (can't forget this one) endow some male patients with a nice rack. I'm not talking about antlers. "Sometimes I talk a little fast and stay up too late when I'm not depressed" does not justify endangering, or destroying the quality of, a patient's life.
Good psychiatrists care about quality of life and patient safety. The good ones favor moderate dosage, least possible side effects, and only bring out big guns as a last resort. Smart, responsible psychiatrists exist; it just may take a few tries to find one. I'll get off my soapbox now...
You don't have to want to be at aa meetings - and they don't work for everyone - but without them I would be dead today.
I do hope you want to live and if there is just a glimmer of hope in your soul - please take the very simple step of sitting yourself down in an aa meeting. If you can do that - and do it again and again - I promise you that your life will change for the good.
In recovery instead of being an emotional vampire ( because that's what I was in the grip of active alcoholism) I now treasure my opportunity to be in this life and to be able to make some positive contribution where I can. I will be a long time dead, just like anyone else and I spent many years only half alive. Today I thank God that for some years now I have been wide awake. Hope you find your wake up moment too, because I know from my own experience it cannot be persuaded, cajoled or forced.
