I had a lot of trouble with the depression, flashbacks, etc as a teen. I have taken more notice as an adult of when it happens, which is late summer/early fall. I really never put it together until my therapist pointed it out a few weeks ago. I thought it was due to the shorter days.

The time of day was much more significant for me. For about 5 years after the incident, I woke up every single night within an hour of the time it happened (3:43am) and stayed awake until 5:30, because I had reasoned that that was a "safe" time to sleep. I was completely terrified the entire time I was awake, but too embarassed to ever tell anyone about it. It still happens occasionally during the Fall. This was, by far, my worst symptom.
