I very much agree with the statement that alcoholics and their codependents cannot be good parents.
I am in the process of divorcing my alcoholic husband, as well as undertaking therapy and going to CoDA & Al Anon groups to deal with my codependency issues. We have very small children, and he might well love them, and is a functional alcoholic so still has a job, but a shit dad. And in the relationship I was a shit mother, as I was so consumed by the insanity of the alcoholism that I was going crazy.
Now that I am out of it, I am slowly beginning to realise quite how dysfunctional it was, the little games that were endlessly being played out. All that attention I took away from myself or my babies and concentrated on him and his behaviour. And I do see the damage it has had on our babies, even if they are little. But at least I have the chance to do the best I can to remedy that. And it won't be easy, there is so much baggage still, emotionally, but we have only just started the journey without him. And it is a relief.
It is no way for a child to be raised, and there was a report out there by Addaction recently with frightening figures about how many kids are living in a family with active alcoholism (3 million or something like that?). I have met so many damaged and hurting adult children of alcoholics in the meetings I go to. That was one of the biggest triggers for me asking him to leave. Realising that I have no power over alcohol and the alcoholic and I could never fix this for our family, I could not imagine my babies having to grow up any longer with it.
I feel like bejeezus, I struggle to forgive myself for choosing an alcoholic as the father of my children. They deserve so much better and he does not really deserve their unconditional love. But I was in denial and he is not a down and out type drunk. He just chose to spend half of their childhood so far getting pissed in pubs, spending all our money, instead of coming home to support me or raise them. I have so many feelings about it, sadness, anger, frustration, fear, fury. And I am really struggling to let go of the codependency. But I am working so hard at that. I was a adult when I got into that relationship, I can only imagine the effects on a child growing up in it. You all deserve(d) so much more and deserve now to take the best care of yourselves.
If you haven't done so before, you could always try Al Anon. Lots of other adult children of alcoholics go there. So I guess to answer the OP, yes many others go on hurting their whole lives, but there are ways to reduce that through meetings, therapy etc. And that will help with the self-esteem and panic attacks (anxiety).
