Hello kumid, it's nice to meet you. Welcome to psych central.
I think that you treatment plan will depend on your Ts style of therapy, regardless though you should be taking a baby steps, I don't think you should have to tackle it all at once or anything. The T that does my group therapy does exposure therapy for ptsd and that involves taking small steps towards discussing you trauma.
