But I haven't spoken to anyone about it. It's not a thought that builds up, it just seems to come over me suddenly. I then have to wait for it to pass. It's a physical feeling. Almost a pain. I feel an urge to slash my wrists, and can feel the pain in my wrists as I think about it.
I know this isn't 'normal', and have wondered recently if it might be a symptom of PTSD.
