stayanotherday, early fifties is too young to be giving up on life. You call yourself an idiot and a joke, which sounds as if you have confidence issues. In that case why not try another therapist, someone who really connects with you?
I love joining groups and even if not warmly welcomed, I persevere, knowing that it’s healthy for me to be with other people on a regular basis rather than alone at home all of the time.
I’m also a firm believer in having a passion for something in life, in my case, art and music. Is there something you enjoy doing when everything else ceases to exist? With a passion like that, it brings a contentment and other things in life fall into place.
Even if not religious, a church which suits you could provide companionship. I have a couple of friends who I know are not really religious, but their lives are full through their churchgoing.
I wish you all the best💐
