Hi Catherine! I am a licensed clinical psychologist, and would be glad to discuss your project with you. I clicked on the link, and based on your criteria, I don't believe I qualify. I do not suffer from PTSD, although there are some people who believe that I should! If you would be interested in discussing this further with me, feel free to contact me through CureZone. Unfortunately, it appears that I am not receiving CureZone emails at this time, so 'Contact' would be the easiest way to reach me. Good luck with your research! That is quite an undertaking and the research is very much needed!
