I may not have read enough about it, but I have seen PSTD defined as being constantly on the alert for so long that it becomes a learned response which is physical as well as mental. Viet Nam vets were fearful of their life for months or years and survived by being on high alert. They learned that that was necessary to keep living. Then they couldn't turn it off.

So, yeah, you can have a milder version of PTSD. Even a milder version than Voidmatrix is suffering with.

In my case, I had a super stressful job in the last decade before I retired. There was an individual who got demoted and I was put in his position, then a good friend of his became my boss, and plant superintendent. This was Kentucky and I'm from Ohio so the good old boy network was firmly in place. My tires were cut, I was assaulted at work,  my 10 year old daughter was approached and had her ear bent when she visited her mom, lottsa pretty nasty stuff.

Enough whining. He was constantly trying to fire me and I had to respond be being 120% for 5-8 years.

And I "won". Kept the job until retirement, paid my house off, raised my kid. It took my every minute and every thought. Took work home. Did what it took

Once retired, pot's a great band aid, but my sleep was not good without it and there was still work to do. I can't be a pothead just yet. Been using the deem's to try to get in touch with my dreams. I was dreaming about being back at work fighting the good fight a lot. A persisting alert I needed to turn off.

That's better, but if life is stressful the work dreams return. Seems I associate that with problem solving and stress. Great progress in that area, though. We'll poke around a little more when less busy.

So, sorry about the too personal stuff.

IMO, what I had/have is a mild version of PTSD.

Yes, PTSD can happen in mild, moderate, and severe versions.
