Hi Weekendwarrior,
That is great that you are making positive changes in your life, the gym, quitting smoking and going back to college. This shows a lot of determination.
I am not sure what you mean by health anxiety.
Is your socialising tied up with drinking? To be honest I could not imagine sitting in a pub for hours talking bollocks unless I was drinking.
I don't know your situation but perhaps you need to find some sober friends and pursuits.
Good on you for waking up to the dangers of drinking and wanting to do something about it.
Respect
