Bro I can even begin to tell you the shit that I've overcome. Long story short, two car accidents. One in 2002 and the other in 2005. Breaking my neck in both accidents. Breaking a leg, shoulder, ribs.....the list goes on...WAY ON. Needless to say, I've been through some shit. To this very day I'm grateful as hell to all the physical therapists I had that basically kept pushing me when I wanted quit. I never thought that I could get to where I am now. So in conclusion, if you stick with the PT, you will be back in the gym in no time and probably exceeding where you were before you broke your arm. Good luck bro!
