I cut myself yesterday. I can't decide if I will tell my therapist or not. He thought I was doing pretty good. (I did too.) Since I'm not going to be here the next time he is in town it will be a month until I see him again. I saw him yesterday, about half an hour after I did it, because I was in the building for another reason, and he asked how I was doing and I just said okay. He was getting ready to go home and I didn't want to bother him.
Up until yesterday afternoon I thought I was doing okay. I don't quite know why I did it. I was surprised because I didn't expect to actually get cut from what I was doing. I'm not particularly upset or anything but I noticed a lot of negative thoughts yesterday afternoon and today and I'd really like to just go sleep for a long time.

The juvenile sea squirt wanders through the sea searching for a suitable rock or hunk of coral to cling to and make its home for life. For this task it has a rudimentary nervous system. When it finds its spot and takes root it doesn't need its brain any more so it eats it. It's rather like getting tenure.
