Any T1D Teachers? Need advice talking to HR/Admin

The district I work at just released our school calender for the coming year and I start back at the end of July and kids return first week of August. I work in Texas and my city had 430 new COVID 19 cases confirmed yesterday.

I talked with my doctor and she is only comfortable with me returning to work if I and everyone else wears a mask. I just don't see my administration backing me up on that.

Is anyone else a school teacher? Are you talking to HR/admin about returning? I was considering resigning, but then I lose insurance. My husband also teaches at the same school, so it probably wouldn't do me any good.
