I've done it! I've finally managed to close off that part of me that wants companionship and hates it to have this empty, shallow life.
So what if that means that I have absolutely no wish to have contact with anybody, and that I'd rather be completely alone in a sensory-deprivation tank, that life the rest of this goddamned life. It's ok, not to miss any of the people I have been in daily contact with for years, and it's ok to watch other people's joys and sorrow with detachment. It's even ok to notice in passing that I am sad, or angry, and feel like those emotions are situated in a part of my body that's not really connected to my brain.
It's ok, bacause it means that I stay sane. I'm not going crazy anymore. I'm as hollow as a drum, but at least I'm a sane drum.
