Prayed for healing

I'm feeling down and depressed because of my health condition this past months. I was diagnosed having thyroid nodules in my thyroid gland. I've been under medication but I felt I'm getting worse everyday. I even feel better before I undergo my medication. Now, I'm beginning to regret going to the doctor because she didn't help me at all. And I have this feeling that she really wanted me to undergo operation. I'm so stressed right now because I always have this feeling of choking and I have a lot of hair fall. 

Dear Lord, please help me. I need your healing power to heal me from this disease. I surrender my condition to You, I know You are our Great Physician. I declare healing and recovery in Jesus name. Amen.
