I can only speak for myself, but pretty much everyone I've told has been pretty supportive. The person who made the worst comment in my eyes was my father, who stated " what, you weren't in the service." My answer to him was , "No I wasn't, mine is from childhood trauma. From the 5years of psychological, physical, and sexual abuse from my brothers." I then proceeded to tell him my story. He Apologized, and now understands why I have PTSD. I sent him an article to read about PTSD and how people can get it too.
Others only know I have PTSD if I choose to tell them, so they are people I am VERY close to; they have been very understanding and supportive. I did have to tell my boss at work and almost had a panic attack, but it went well and he now understands why I can't work with kids who get to physical with us. I hope it gets better for you as you get more comfortable with your diagnoses.
Welcome to the forum, I'm glad you found us as people here are very understanding and supportive.:) But, I'm sorry you have to be here as it means you too suffer from trauma. Welcome again, I do hope you find what you need to help you in your road to recovery. :hug::hug:
