@Blunderbuss,
I was in a similar situation almost 40 years ago (albeit male and four years older than you are).
And I've been sober ever since.
I am firmly convinced that if you want to give up alcohol and lead a different, new life - then you can.
You and only you - not a psychologist, not a psychiatrist - decide how things should continue with you.
You have already experienced for yourself that alcohol can make you forget anger and worries for a short time, but that this anger and worries can, so to speak, swim in alcohol and even get bigger as a result.
You alone decide how things should continue with you. And will continue. Accept the help that is offered to you on the way to a new, better life.
