Hi there! Welcome to the forum! My name is Lise and I’m 17. I have had T1D for 4 years, I was dxd just a few days after my 13th birthday.
There’s another thread on the forum called looking for t1 teens. There are some teenagers ages 13-20 who are occasionally active on there and you could reach out there to see if any one is willing to connect! Your daughter is not the only one.
Last year I went to a regional Friends for Life conference, organized by the organization children with diabetes. I made a few friends with t1d that I’m still in touch with today. It’s an awesome place to meet people of all ages who live with diabetes- from 2-70 or more years old. My mom was also able to connect with other parents who have kids with T1D, as well as adults with T1D which was something she enjoyed.
You could also ask your endocrinologist if your clinic does meet ups for kids with T1D. My clinic organizes an activity for teens with diabetes every few months and those can be really fun to go to.
