PTSD, ADHD and chronic fatigue, depression, depersonalisation, or other debilitating conditions,.are way beyond you, my friend. I get it though, you're searching. I've searched for a decade. Doctors dont know or care, people don't get what happened.
Here's an example of a salvia PTSD flashback. You open a bottle and your heart jumps because you think when you open the bottle, salvia will be triggered and god knows what will happen to your reality but you think up a pretty weird salvia themed scenario, and everyone will be in on it, even your best friend who is there, and was - Truman style. Its a split second, you jump inside, the weird scenario from that tiny flashback plays with you for days.
