Wow Jadebear, a lot of this sounds familiar. When I told my therapist in 2008 about the details of what happened to me I suffered many of the same feelings. Would I be judged/believed/and felt lingering feelings that my life was collapsing around me. Problem was, he did not go through it with me or do any real therapy so I simmered in some pretty horrible depression for about a year. It sounds like your therapist is "with" you and that is a huge asset. As I was going through all this I felt like I was going to die--a bit different than your situation--but it produces some desperate and uncomfortable feelings. I got through it but you feel like you are wading through a cesspool in the process but you do come out the other side.
I suffered with PTSD for so long that I had these weird feelings that went like this: I just turned ten, what will 20 be like, will I live until I'm 20, will I get to be 16 and drive and then graduate high school? Then when I turned 20 I spent the majority of that decade wondering if I would make it to 30 and I dated little thinking what's the use, etc. and it went on through life like that until my 50's. This is part of PTSD--a foreshortened feeling of the future. For me, putting all these graphic and disgusting (I felt they were) things out into humanity was very overwhelming. Have you and your therapist talked about a safety plan? If not you should do this. For example, do you know how to contact your therapist if you need to? Do you have friends you can hang with if you need to and you can't get hold of your therapist? If you start feeling suicidal do you know what to do? Do you know where the hospitals/emergency room/mental health resources are if you need them? Can you get access to medication if you need to from a psychiatrist/primary care physician? Can your therapist talk to that person? You can sign consents and releases in advance and make them good for a year so communications can be expedited if you need to. Ask for a treatment plan that outlines therapy approaches so you can have something written down to look at when things get confusing and you feel like you are frantic for the next step.
When I stirred everything up by really talking about it for the first time, I felt feelings of doom; I felt stalked and hated to go to sleep because I would have nightmares. I thought I heard noises and when the ice maker in the refrigerator kicked out cubes I would jump out of my chair in the living room where I was sitting. I swore a random noise was someone at the door or in my basement. In short I felt very paranoid and unsafe even in my own house. It is better now but the fear and anxiety is definitely kicked up a notch while I was putting things out on the table. Hang in there and keep close to those you trust and try to be around things you find grounding. The people here on the forum are with you but keep your contact in the real world close at hand. Every-ones' experiences are different but we all have a few common threads. You can make it and survive it. Your last sentence of your post IMHO is dead-on target.
