Hiya,
I feel very much like you described. I haven't worked much in ten years. I gave up on looking because it was stressing me out to not get jobs I applied for. I say I retired early but that just makes me feel better about it. I don't do a lot either. No social life really. I hardly leave the flat. I have to work hard to get out for a walk. I potter around on the internet. I manage to avoid too much spending, but I have my moments. I have discovered Scrabble on facebook and I play the occasional game. I enjoy it but I sometimes have words going round and round in my head. That happens if I try to lie in in the morning. It was particularly bad today. I think it is a hangover from the Seroquel that I take at night. I have suffered from Bipolar Disorder for over 27 years. I don't get too much in the way of mood swings, but I do suffer a lot from anxiety.
I wish I had some coping ideas for you. I am very much in a similar state to yourself. I just want you to know that you are not alone.
Regards,
Clive,
