Great thread Kata and congrats on doing what you can to take care of yourself. You sound like a wise woman.
I read a lot as a kid and many of those books I reread as comfort books now: Daddy Long Legs, Little Women Little House Books and anything by Georgette Heyer.
Like Healthyagain, I knit but most of all I just love to go to knitting stores and sit amongst the beautiful yarns. Many of these stores have tables or comfortable chairs where you can sit and knit or crochet.
I'm a depressive so exercise of any kind is a huge help. Also just getting out and trying something new or being with people even though I am an introvert of sorts.
