Has anyone found anything that helps with PTSD symptoms

My PTSD is really bad right now and is causing a lot of problems with my personal relationships and social life. I was diagnosed years ago, and two years ago I went through a really traumatic situation that resulted in repeat situations that caused great trauma. I almost lost my life and all this seemed to cause my PTSD to get really bad.
I thought I was doing better recently and I realized I am not. I am numb, I am on guard all the time and trust no one, I mean no one. I stopped talking to friends, no longer want to go out, and be around people. I can't stand being around crowds and forget even going to the store if it is crowded I get real bad anxiety and need to leave.
It causes problems in my relationship because I am always defensive and suspicious. I am sick of living like this I am a nervous wreck all the time, I can't sleep, have nightmares so I am exhausted all the time.
I am in therapy just started a month a ago with a new therapist,and I really like her, she has a lot of knowledge about PTSD something I have had a hard time finding. I guess I am impatient and want a quick fix. I am only taking buspar and it does nothing, and blood pressure med at night the doc said would help me sleep and stop the nightmares, well it hasn't worked at all either.
I guess I am just trying to see if anyone has found something that actually helped them. I know there are a wide range of meds, I just do not want to take a med that will sedate me or cause even more issues. It seems everything lately triggers me, so I avoid things more and more and my moods are all over the place.
I am not seeking just meds anything maybe a certain kind of therapy I do not know. I do like to paint that helps keep me distracted for a little while, then those wonderful intrusive thoughts come flowing through. I used to hike all the time but so paranoid I cant seem to drag myself to go anymore.
