Jerrie It is so frustrating when you get no answers from the doctors! Been there with my husband. They could tell us what it wasn't but not what it was. This was several years ago and we still have issues with his health.
Just hang in there it will get better. When you're down you can only go up!
Talking it out is the best thing you can do so please come and vent whenever you need to!!
Keeping you in my prayers! Just take a deep breath and let the Lord help you and keep you in his hands!
