I think I just bricked my character, is there any way to solve this??

I made a character to go demon form which stacks life reducing items as the more life you have the harder it is to sustain. In act 1 cruel I killed the candlemass and without thinking clicked the item it gives you for killing him which gives +8% max life. So this just gave me 8% more life which I am paying several divines in items just to reduce my health by that much... Is there any way to undo this or am I going to have to reroll...

AHHHHHHHHHHHHHHHHHHHHHHH T_T
