Good Luck at your Dr's appointment. That's a shame they changed your appointment to almost a week later. I hope it's not Diabetes that you have but if it is, the Dr's will give you all the tools/information you will need.
My daughter 2 years ago at age 20 was diagnosed with Type 1 Diabetes. The Dr. put her in the hospital to get her blood sugar under control. She is on needle therapy. Right now she says she doesn't want to get the Insulin Pump because she doesn't want something permantely attached to her body. It's a personal choice. I pray that a cure for Diabetes is in the near future.
