I have decided to distance myself socially due to myself being a danger to myself and other's mental health.

However, I saw one of my friends somewhere, and while it was a small, brief and what should've been otherwise commonplace sighting, it filled me with sadness, and I almost cried. (Big deal for me due to asperger's)

I don't know what to do. I think I miss them, but at the same time I don't want to hurt them. I've chosen a distance period of a month.
