God does wonderful things for us. He wasn't ready for you yet, and this was a warning. So glad you found out what was wrong,and apparenty you can be (repaired). Wishing and praying for a successful recovery.
Another body part that can make you feel totally exhausted is your Thyroid. I found that out when it was out of sync at the health fair. Took meds for a yr. for it, then had a biopsy done and went to an ENT and he suggested surgery. I had a total thyroidectomy June 2009, turned out that I had cancer in my left thyroid. But so far 2 yrs later no sign of cancer anywhere. I get a checkup every 6 months. God has blessed me and isn't ready for me yet either.
