@RatWrangler Mental pain should never deemed incurable.
I agree. The only exception I can think of is if someone also has a fatal disease (from which they're likely to die within a few months) in addition to their mental pain.
PTSD can be very painful. Flashbacks often involve reliving an event and experiencing the physical pain as well as the terror. I sympathize with people who no longer want to deal with that. But how can anyone know it's incurable? The same thing applies to anxiety, depression and many other problems.
PTSD also distorts my sense of time. When I'm reliving past trauma, I feel like I'll be in that moment forever. Kurt Vonnegut described it well
"Listen: Billy Pilgrim has come unstuck in time. Billy has gone to sleep a senile widower and awakened on his wedding day. He has walked through a door in 1955 and come out another one in 1941. . . . Billy is spastic in time, has no control over where he is going next, and the trips aren't necessarily fun."
Even after the flashback, I often feel like things will never change. Depression can also feel like it will last forever. But it doesn't. I haven't felt suicidal since I stopped taking antidepressants (against medical advice). I would have never predicted that. Neither did any of my doctors.
My PTSD, depression, and Tourette's have gotten much better or worse from meds I've taken. That can last for years after I've stopped taking the med. Who knows what new treatments will be developed or which new environments or other life changes will help (or hurt)?
