Hi catlover, welcome to PC and the PTSD forums. The answer to your question is "yes" a lot of people who struggle with PTSD struggle with anxiety when it comes to therapy. However, this challenge "can" ease up once you get so you settle into the therapy. Anticipation is often a common challenge with PTSD. Be kind to yourself, do your best to just put one foot in front of the other forward. You are not going to be expected to do things you don't know "how" to do yet ok? Often what they will also do in a group is teach you ways to help yourself when you experience these panic type attacks, you will not be the only one there that is struggling this way.
