I'm sure giving up your second job was hard. But, taking care of your health is worth much more than any paycheck. I'm glad your DH is supportive of you.
I despise going to the dentist, too. I don't know why. I had rather go to my gynecologist any day.
I am sure that it was very hard to give up a job that you enjoyed...but your health is important and I am sure your hubby wants you around in the best health possible!
