Hi Beth, welcome to the forum. It's great that you have joined as there is a wealth of information on here and lots of great people who want to help others.
Your levels are a little on the high side and I won't nag you about the importance of keeping good control (i'll leave that to your mum), but in all honestly if you can get your levels a bit lower that would be beneficial to you in the long run. Complications from diabetes don't happen overnight, but over the long term higher levels can lead to them.
I have 2 children with type 1 and my husband was diagnosed with it when he was 14, so although I don't have it myself I am surrounded by people who do!
Hope you get as much out of joining here as I have.
Leggott.
