There's definite mental health pros in giving up.
I never believed my drinking and drugging was affecting my mental health - but now in hindsight it definitely was.
I had a very dark worldview (and self image) that came at least in some measure my poisoning my mind and body on a regular basis.
at my worst in active addiction I was agoraphobic and paranoid, but even at my best there were repercussions.
My depression and anxiety were two of the things my drinking did absolutely nothing for and in fact made worse.
