That's wonderful! Be proud of yourself. As someone else who has been ducking out on going to the doctor for a long time, it can be damn hard to screw up the courage to go in.
Seriously, I hope that one day, I feel as strong and empowered as you.
(And try not to be too nervous. You're gonna get there and go 'I was nervous about -this-?') Really, big congrats on this one for seizing control of your health.
