Hey Precious
Thank you for your post. I do relate, very much.
Get a new therapist. Dealing with your husbands infidelity sounds like its very important. I think you are saying your alcoholism is your way of dealing with it and obviously that's not working. I will add my own experience here. I had to be 'willing' to let go of my anger, feelings of betrayal etc. I had to be willing to forgive. And I had to be willing to forgive myself. I'm a work in progress.
I would definitely look into a program of recovery. Preferably one with meetings so you have others to talk to, and listen to. Someone in a meeting said something funny, but also very true for me "Its ok to sit on the pity potty every once in a while. Just be sure to flush". Haha. That's a good one.
If you want to feel better, I believe you can. But it does take action. Its hard, believe me I know. I'm struggling with that right now.
Your post has helped me. And congrats on 2 months sober. Now maybe make today a sober day because YOU choose it.
