Type 1 diabetic class 1 medical
First, let me say good luck following your dreams, the sky is an awesome place to be.
We have one captain on our books who became diabetic. He is filling an office position and trying to get cleared back in, at least as a sim pilot. The problem as you rightly say in your case is that yours is pre-existing. I think it will be very tough for you competing against other applicants without diabetes. Recruiting staff are not famous for taking risks...
