need help making my build tankier

right now im a crit glacial cascade inquisitor.

for my gear look at the gear of my character "MrZapZap"

I would rather not replace those 3 uniques if possible.

my life is sitting at 3790 atm (have more life nodes to get still)

my crit chance at max power charges is 78%

I am having some difficulties surviving at the moment(if I play careful im fine but I cant afford to max speed through the map atm)

I am looking for suggestions to make my build a bit sturdier.
