I don't know if you mean me (Tom), or another Tom on here, I am 100% disabled from PTSD, so i know a little about it...I found that it has no rhyme or reason, one day i was happy and carefree, and the next i was miserable, but i found out with therapy (2x a month) and people with simular problems and a great therapist, and an understanding family, i'm back to my ole self again...My therapist said its like a switch that just comes on, and it usually goes off, but when you've seen too much action and in my case i had retired and i was too relaxed wih very few worries and it reared its ugly head, and took quite a few years to get control of it...There is no cure you just have to keep it in check, i have refused to take any meds, because i have seen first hand the zombies that the meds produce, hope this helps somewhat...
