After I linked you to the secondary diabetes thing above, I did a bit more googling. If you put in some of your medical details along with the word “diabetes” you’ll find websites mentioning diabetes after certain medical problems. Hopefully that will help a little to show you that you’re not alone.
This is a better general link re secondary diabetes as it actually gives some causes and compares it to Type 2:
Secondary diabetes is a different condition than type 2 diabetes. It’s usually caused by other medical disorders that affect glucose tolerance.

Most Type 1s don’t have a pump. I do. I wouldn’t say it was easier than injections. It’s a fair bit of work.
