Hi. Welcome.
I'm glad you're here, and I'm sure that you will find this forum useful. We're all welcome to post wherever we like on here, but one area that may be specially useful to you is the Friends and Family area....
https://www.soberrecovery.com/forums...ery-plans.html (Psst...wanna know why I'm always recommending recovery plans?)
Lots of people there will have experiences similar to your own and found various ways of coping and minimising the effect of addict family on themselves and their potential for a full and happy life.
Have you accessed any of the support groups that are avaiable to you locally? If not then it might be worth investigating these.
ACOA (for adult children of alcoholic parents) in particular might be useful - even if only drawing on their online resources or literature.
Adult Children of Alcoholics
Nar-Anon or Fam-Anon may be useful as well. If you google those things along with your country you'll be able to see what's available for you
Anyway. Again, welcome.
BB
