HELP ME PLOX - Noob Maurader

I am having a lot of trouble in act 2 cruel and am not sure what I am doing wrong.
Probably didn't do enough research before playing my class and would like to know if my character is even still salvageable. Its come to the point where I die every two seconds and its incredibly frustrating for me.

So if I could get any tips and or tell me which skills I should be using that would be awesome. Also if I should be two handing or 1h etc. etc.





long story short should I re-roll
