19 M, Diagnosed With Type 1 ~6 Months Ago. Anything I Should Know?

Im 19 and from the U.K., I was diagnosed with type 1 6 months ago, I'm "honey mooning" pretty hard right now and don't need insulin for meals such a sandwich etc. and my blood sugar is around 5-6.5 mm (don't know the us measurement)

Basically I'm looking for any advice that could help me in the long hall, thanks!
