There's no better person to talk to than your therapist. She can get to the bottom of your situation by you being completely open and honest with her. Do you feel your PTSD is from your childhood? You can't fix what what you won't acknowledge. Everything you tell her is confidential, and keeping things from her won't hurt her, but it also won't help you. If you are seeing her already you must want help, and are open to receiving it. Make her job a little easier by letting her know all your concerns. god luck.
i would talk to a therapist maybe a psychiatrist :)
