My, my, my...
I highly recommend you talk to your doctor about this privately. She will have more influence at this point in their decision making, if she is willing to help. You might want to share this thread with them. I will speak to my experiences (50 years of Type 1):
When I became diabetic there were no pumps--you could not even test your blood sugar. Until pens came along, I had to be home to take insulin as we used a glass syringe with a metal needle. This just adds background about my parents situation.
I had a very wise mother. I was also an only child and Mom know I needed to socialize to be normal in some way. She encouraged my partiicpation in activites--I did a lot of theatre which involved late nights, a trip for soda after a rehearsal, etc. Remember, you could not even get a diet soda in a restuarant at that time, so it was really tough for me. I moved away from home to go to college. Yea, I made mistakes. Yea, there were some scary moments--lows she had to rescue me from (they always called her--never helped me treat,) a couple of hospital stays (they slammed you in if your glucose was too high, as you could only test in a lab.)
However, I am now 60, have a wonderful husband and a great son, as well as two beautiful grandchildren and just retired after a long career. I went to college, worked overseas (before being married, so I lived alone) travel extensively now with my husband. I could go on....
Oh, and my only complication is some very controlled retinopathy.
The point of that is not a brag, but a real life illustration of how a type 1 can have a really regular life. But that type 1 must have the skills to handle it all. The only way you learn to fly is to have wings. Your parents owe you that.
