Barb,
I'm new to this site and I truly understand where you are coming from. MS is truly awful and is a lot to deal with along with everyday issues even if 100% healthy. Some of the posts can be depressing and discouraging but I find a lot of useful information and sometimes its just nice to know I am not alone with this MS. You have to do what you feel is best for you. I hope you find something that makes your days brighter. I want to take a break from life, but I must struggle on. I am not an optimist, I am a realist.
I hope you get what need while taking a break and come back even if is just to check in.
Take Care of yourself,
Sheila
