Separate from my sobriety - is a big pile of life long mental health things- that need a GP for medication (major depression mainly) and a psychologist - which taught me how to use CBT and ACT, both of which helped a great deal.
I also did volunteer work joined art and writing groups, walked a lot, made myself go out and go to meetings- where I have met people who are now friend I have coffee with, as friends.
I was as low as a human could go when I stopped boozing- and it takes time and work- but the outcomes are worth it.
