Picard was tortured by Cardassians (pretty efficiently, as we saw in the end), assimilated (a trauma which affected him throughout his life), relived a whole (fake) life where he had a wife and children whom he "lost" when he returned to reality (he showed in that episode and later ones that he cared), he "died" and saw an alternate version of himself who didn't take risks... and much more.
I can only ask myself, how come he is still the captain after all that trauma? How come he didn't get PTSD or a similar condition? Starfleet did send him away after the Borg incurred into Sector 001 for the second time just to be safe.
How come this man keeps his sanity after all those traumatic events?
