Namechanged12344 totally agree with you prioritise yourself for counselling, that way you will be in a better position to see things clearly and help your DC. The benefit being, drink can't be to blame.
In my drinking days, when I used to wake in the night with heart pounding/sweating/feeling sick attempting to piece together what I had said done, I remember my DH saying 'I need to talk to you'. OMG, and he would leave it hanging until he was ready to tell me what I had done/said. I dreaded that, like being at school again. I felt weak and worthless. So now, like last night when my DH said 'I need to talk to you ' 😯 I initially froze, ran through my memory bank and thought no, no drink involved bring it on. It was just about buying my DD a new phone 🙄.
What I am trying to say, is once you remove alcohol, you can see things clearly, are responsible for your actions and things are easier to deal with.
I really feel for you, I was so lucky my DH supported me when I needed it, so no pressure. I get the f* it feeling, I still get it, but it only makes you feel worse.
Believe me, when you wake up and it's a bad day at least you are aware of your behaviour and don't have a hang over. I really felt I could trust myself again, stay strong, it is worth it. I know how hard it is. No one ever regretting not drinking the night before. Take care. keep posting. Happy to support you via DM if that would help.
