Welcome to PC & The Complex-PTSD Forum.
I found this book to be a big help ...
You can buy a copy at Amazon ... If you are unable to buy a copy, the author also has a website with lots of useful information ...
Pete Walker, M.A. Psychotherapy
I also find interaction with people to be very difficult due to trust issues and am not sure if I'll ever be able to completely overcome it or not ... But I do keep trying, and that's all any of us can do.
I hope you find this site to be supportive and helpful too!
