Knitting as therapy

Have you ever just sat and knit something, usually a swatch for nothing in particular. I found myself doing that the other night. I literally knit for hours, and yet made nothing. I'd get to a certain place in the swatch and rip it out, then start over again. All the while I was doing this, my mind was focused on some problems I was trying to come to terms with. Even when I'm actually knitting on a project, I usually find myself in this "knitter's zone", and sometimes don't even notice what's going on around me. I find I'm calmer if I have needles in my hands. If I'm in a situation that makes me anxious or uncomfortable, I either grab my knitting or I wish desperately that I could. So I've decided, as no doubt many other knitters have in the past, the knitting is my therapy, my Xanax, my method of coping with pressure. I just hope I never have to do without it, would be to horrible to imagine. Of course, with the size of my stash and the number of needles that I've accumulated, it will be along time before I'm without the equipment I need to cope with life.
