You may not be following this thread, as I see the question was posted over 5 months ago, but here's another experience.

I have attempted to go to community college 4 times over the years (I am 45 now). I am currently attending, this is the longest I've been able to continuously take classes (one year) and I've got a 3.8 GPA. I had a PTSD related episode a few weeks back and it has adversely affected my grade and my subsequent attempts to retain the coursework. I have my final this Tuesday and feel real despair about the outcome, although I've discussed it with my T and know I can/should get past this.

I did not disclose - I don't think there are any accomodations they could make, nor would I want to be singled out. Maybe I just don't want to be open about it to myself, I don't know.

Good luck with your research, and if you've already finished, I hope it helped you to understand PTSD better.
