Yes, PTSD has affected how I act/feel in therapy. I am always "very tired" after therapy and kind of spacey the next day. It took me a while to begin to "trust" my therapist too. I was already hurting to a point where sometimes I didn't want to interact and get triggered to feel worse.

It took me a long time before I really talked about my childhood. I didn't feel it had anything to do with how I felt in the present. After I began to talk about it, I realized how much it "did" have a lot to do with how I am/struggle.

PTSD tends to "magnify" our emotions/reactions so because of my history of the way I was abused/bullied/misunderstood, it was very important to me to have a therapist that was "not" pushy and judgemental and especially "not" dismissive.

One day I was very motivated to get big poster sized paper and write down the things that were upsetting me. It seemed to be to only way I could release my inner frustrations. I ended up taking that to my therapist and he told me it was very good for me to do that, anything that helps me let things out is important. Sometimes it can be very hard to put things into words when someone struggles, especially if they had a history of feeling that speaking up was not something they were allowed to do growing up.

It can be a challenge for some people who struggle with PTSD because they often don't have the "language" to express the things that can deeply hurt/trouble them. So what I learned is that it was important for me to pay attention to "all my feelings" and put them into words in whatever way I could.
My therapist has consistantly "validated" me every step of the way, which helped me to gain momentum in finding the language to go with how I struggled.

When I first joined PC there were different things I posted to that helped me to just "talk and think" one step at a time. At first that was very hard for me to do because my mind was often "racing" with too many thoughts so it was an effort to focus and slow down.

Ofcourse I am older, so I have had more time to adapt and develope inspite of my troubled past. If I was younger, I may not have responded to therapy as well. I did spend time with poetry, art, and music which gave me a way to express myself with language without directly interacting and feeling the pressure of being judged or hurt.

Each person is a little different in how they find ways to "express" themselves, if they tend to be quiet and shy, PTSD can maginfy that.
