I've had problems since I suffered psychosis 1 1/2yrs ago with a recurring need to be strangled. I have no idea why, and have often found myself in bed at night with a cord round my neck, but not too tight. When my nurse asked me yesterday if I had SIed recently I immediately felt so guilty and couldn't look her in the eye. I haven't told her about this- I don't know what 'this' is. I mean, is it actually a form of self harm. I am not harming myself, and it is causing no injury. I am totally confused, and while I used to be more worried about the actual act of it, it doesn't seem to be much of an issue anymore coz it is not too tight round my neck. I am totally confused, feeling full of guilt, and ?ing what it actually is that I am doing...
