Hi Amandalouise: First thanks. Your reply was helpful and most informative. I kind of knew about endorphins being released A couple weeks ago I accidentally nipped my hand with a sharp knife. I was trying to cut the plastic wrapping off a package of ice cream. Grrr the way so many packages are tamper resistant you need a Phd to figure out how to open them. OTOH realize its for our safety. I was going through a very rough day emotionally and when I nicked myself my emotional pain left. Don't want to go into what happened earlier except when I was at the supermarket a favorite song of my ex boyfriend was on the loudspeaker. It was very traumatic. I see in 2013 dissociative and self injury disorder is named called non suicidal self injury, Both are mouthfuls. . I don't recall ever experiencing delusions,etc My dxes are OCD ADD Bipolar, PTSD. Tourettes for the record but that's neurological. My other diagnosises are concurrent mental disorders based on my TS and my PTSD. BTW I was born in the US and I still live there.
