You might take a look at your alignment in your form. Get both of yours shoulders pointed in alignment at the target, straight bow arm, and proper back tension and the bow weight will feel lighter. And maybe cut down on the number of arrows you shoot in a practice session...fewer arrows each session, but shoot more often.
Is 32# enough to kill deer? Yes. But can bad things also happen? Yes, specifically if you hit a shoulder. Hit a shoulder on entrance and it likely won't be a fatal hit, one lung at best. If you hit the far shoulder you won't get an exit. You'll most likely have a fatal hit but without an exit, you might have a challenging blood trail.
I would stick with broadside shots and forget about the quartering away angles in which you are essentially aiming for the far shoulder.
3:1, straight edge broadhead with the ferrule no larger than the insert and shaft, micro diameter shafts. And make sure that you do not short draw. Guys like us with short draw lengths do not generate as much energy as a string bean drawing the same poundage at 29" or 30".
