Welcome, Pinkmoon1..I have had the same sort of revelation. Here thinking I needed to learn about PTSD so I could understand my friend and learn ways to manage my own feelings/behaviour. I learned that my mom is has these PTSD symptoms, though she was never diagnosed, she coped with alcohol, etc but it made for a rough upbringing. I think I myself may also deal with some of the symptoms and never realized it for it what it was, always thought I was a depressed, co-dependent, adult child of alcoholic. This forum is truly eye opening with a wealth of knowledge and understanding, supportive people. It is a great feeling to know you're not alone, no matter where you fit in. (as supporter or sufferer). Wishing you the best.
