Not entirely drinking related, but looking back - more than likely partly related - I used to attend group CBT sessions for anxiety and low self esteem. Without fail I would pick up wine on the way home by way of congratulating myself for going to the session.
This was long before I had admitted drinking was having a negative impact on my life. I still remember and have the tools learned, but I wish now that I'd given it my all at the time. Still, we can't change the past!
Definitely don't isolate yourself, the enjoyment that comes from catching up with friends whether you tell them or not far outweighs the annoyance (insert relevant negative feeling) of cancelling due to a hangover - I've done this far too many times
Good luck bumble, sounds like you're on the right track
