Hugs, James... I hear you... that was my m.o., too, just as you wrote:
"Here's what I think sometimes: be polite its the done thing, I want them to like me, I dont want to upset them if I dont laugh, is something wrong with me because I cant be relaxed and happy, will they think im being rude if I dont laugh?"
It's so difficult to break out of that old remote-control mode. In fact, I practically did enter a cocoon, for several years, mostly staying home and tending to my family, with very little outside contact. Writing, especially here on this board, has helped alot to shake loose some old rubbish inside me... and developing my personal relationship with Jesus Christ - trusting Him has freed me up to not be so concerned about not trusting myself... whew, that was a biggie. After npd-ex, I didn't trust myself to be able to manage much of anything, let alone make any decisions.
But James, you're already getting out alot of old junk which hasn't served you very well. You are SO on the right track... and I know that you will make it through. I hope that you don't have to go into seclusion in order to make the changes... at least not disappear from here, for too long. I really appreciate you and wish you all the very best as you continue to grow and heal!
With love,
Carolyn
