hi and welcome kph
I got to the stage where I could only be happy drunk or high too - thats actually a pretty big red Addiction flag.
The next phase after that is brutal - when you find you can't
be happy anymore, no matter how much you drunk, snort, shoot or smoke.
You're wise to jump off now rather than later.
I think anyone whose life revolves partly or wholly around alcohol is going to be a little bereft when they stop drinking.
Happiness and joy do come back - but it may take a little while - after all we drank for years, right?
Give your body & mind time to recover
How long has it been for you?
