Hey waterknob, you passed your DOT physical!!! That's great news!!!
And the blood pressure, the chest pains.........well it's completely understandable if you're still feeling under some stress/anxious which could effect those.
Afterall new job.......plenty of "unanswered questions".........but it is a positive move remember, away from this job and all of those negatives you've been experiencing, into a job/a career in an area you are passionate about.
So with that visit to your doctor, and a little less stress...........
But don't forget you gave this job your best, more than your best for plenty long enough. Like we've said there come times when you have to put yourself first.
And some of your friends there well maybe you could still meet up with them after you start your new job??
And patients.........while I'm sure some of them will miss you too, they'd want the best for you as well, right??
So another CONGRATS on this move ahead!!!
