Who has told you you are type 1? Is it an endocrinologist?
On what basis have they determined you are type 1? Have you had a cpeptide test and a gad test?
It would be pretty unusual, and poor practice, for someone to be diagnosed with type 1 diabetes and then left for a week without any medication.
There are 400,000 people in the uk with type 1 diabetes. I'm sure the vast majority of them just get on with life exactly as they would have done without it. One of them is, currently, prime minister.
