Welcome to the forum Auburnazd.
I am in the same boat as FlyingDutchMan.
I have no experience with what you have gone through and can only agree that you being in the hands of professional care is your best bet.
The only advice I can give is; don't pick up again. There is no situation where smoking and drinking will help anything.
Wishing you the best.
