I don't have any children myself. Heck, part of the reason I don't have any children is because I'm too much of a worrier and I know it, situations like this would drive me batty.
But I just wanted to let you know that this section of the board is often slow, so don't get discouraged, someone in the same situation will find this and post. In the meantime, you're probably right that you'll laugh about this in a month or so. It's hard to let go. I'm a type 1 myself, but I was 28 years old when I developed it. My mom will be retiring in 1-1/2 years and then my parents are planning to move from Minnesota to Florida, they have a house there already that was willed to them by my grandparents. I'm 35 years old now, and my mom is worried about leaving me "all alone" in Minnesota.
Over the years my mom has developed a habit of calling me each and every morning to make sure I'm alive, that I've made it through the night. I know she is really looking forward to moving to Florida, and I know she is also torn up about being so far away from me and unable to help if there's an emergency with the diabetes. I am encouraging her to move to Florida, because she can't "hold my hand" for my whole life, she needs to relax and enjoy her retirement.
Anyway, long-winded today, sorry about that! Just wanted to let you know that I can understand how you're feeling, but it will be okay, you'll see.
