Your go-around and divert was clearly spot-on.
Speedwise: Warrior II POH approach speed is 63 at MTOW. Solo at half tanks, probably about 59. Even with another 5kts "for the wife and kids" (which I'd not advocate) that's 64kts.
I'd suggest practicing working out, and trimming for, the book approach speeds. You should find it makes a big difference to both your stress levels and landings.
