Hurt/Comfort and PTSD

[chordatesrock]

I wrote something for fun at one point. It was a scene from the point of view of a character with PTSD, set immediately following the part of canon where he returns to the exact location where most of his trauma occurred. If I were to draw a graph where the Y axis represents being more mentally unwell, and the X axis represents time since the end of the original trauma, then I might draw a line sloping shallowly downward as it heads further right, with a bump in the middle. The fic would be that bump. It has its own beginning, middle and end.

( I hear bad things about H/C, and I think this fic might be H/C )

Because I feel uncertain about this, I would like to invite the thoughts of anyone with relevant experience or information.
