Hi Sharon, and welcome to the forum - though sorry you have RA. Like you, I was diagnosed fairly quickly, but it still took a while for it to sink in. I was diagnosed in January 2006, and had a tough 18 months, but once on the right meds things improved considerably. MTX didn`t work for me, unfortunately, but most people do well on it.
I`m a retired teacher - I taught PE in a big comprehensive for many years. After two lots of Achilles surgery I was advised to stop the PE, so until my retirement I did some RE teaching, and a bit of Special Needs.
Good luck with the job, and with the sky dive - very brave of you!
