this is one of the reasons i was in aa meetings 24 / 7 if i could as when i was out and around the meetings i felt much better about me and my head had no chance of dragging me down
but when i was alone in my flat i would always be feeling pain hurt guilt and fear, my head just would look for anything i could worry about
so for me i found my cure was to get to meetings day and night and tell them how it is people would come back with me after the meeting and we would have a mini meeting at my flat as they kept me company
i owe a huge debt to those people in aa who went that extra mile to help me just by being there for me to talk nonsense to
it got me through some of the huge downs i was feeling and i found the strength to just keep on plodding on
of course there were plenty of kicks up my backside to follow as i found out that i would milk feeling down and unhappy and ungrateful for all its worth but that came later on
good luck to you
