Hi granite1. Are you doing ok now?
Urges can be specific sometimes, at least from my experience. I would get blindsiding urges seemingly randomly every now and then. I mean, just the other day I wanted to break my arm. For no reason whatsoever. These urges can be very hard to pull away from, and I'm glad that you posted on here to help alleviate the strain.
Please be safe, and reply back as soon as you can!
