Paulos, I don't know if this will help or not, but early in my recovery, I was so in my head all the time that when I was isolated, all I could think about was what I couldn't do, and not the little things I could do.
The more I thought about what I couldn't do, the more it magnified those things, and I got terribly frustrated.
That's why it was so important for me to get out of the house, go to meetings and interact with other people to get out of my own head.
Just my thoughts on on the the subject.
