Hi....first let me say I am pretty strait forward so please dont let it offend you, I just have trouble getting my thoughts out, so I kindof "blurt" it out.
Having said that. I understand that you have problems from the past. A true diagnosis of PTSD cannot come from a "counselor". Yes, they can give it their best guess, and they can very well be right. But, only a full psycological exam can "label" you with your dx. I would suggest that you get one and then if medication is something you want to look at...well, thats the one you should get it from....the psychiatrist.
I am dx with PTSD. I also was forced into groups....for almost a year. FINALLY the doctor came to the conclusion that it was not helping me to be in group and had me just get individual therapy. With PTSD....fear is part of it and it does not go away.....until you get regulated on meds and work thru it all with therapy....it is best to avoid the situations that cause you trouble. There are meds that help and I believe therapy helps, but it all takes time. But, let me say, I dont believe meds alone can help. Therapy is essential. You have been traumatized, you need to find the RIGHT ones to aid you in healing. And yes, it has alot to do with the way we think and we DO need to change our thinking. But, we cant do it by the snap of a finger. Find a doctor that you trust and believe in and that UNDERSTANDS the condition (a specialist in PTSD). I too went thru many counselors.....many psychiatrists.....and now am in EMDR therapy. You might look that up and might be an option for you....
I take Klonopin for anxiety/panic
cymbalta for depression (PTSD causes depression usually).
Good luck and I dont know if I helped at all....but look up EMDR therapy and at least think about it.
