Hi there, I am exactly the same age as you, diagnosed Type 2 five years ago and had to be switched from tablets to insulin pretty quickly. I think you might find it is actually easier in some ways to be on insulin and at least you won'thave upset tummy or anything from medication. To begin with you'll need to keep a very close eye on your blood sugars and if you have good diabetic back up at your local surgery or hospital clinic, that will be an enormous benefit to you in the early days. You might go through a "honeymoon" period, as I did, when my readings became near perfect and I actually wondered if I could come off of the insulin but unfortunately that stable period didn't last and it takes a while to get your balance right for you. Everyone is different, so what is right for me or anyone else on here, won't necessarily be right for you. I worried about hypos in the early stages.....that I wouldn't recognise the symptoms but trust me, you will. Always carry something sugary with you and your test kit. You'll soon settle into using insulin. The actual injecting becomes as unbothersome as brushing your teeth.
I still don't have "perfect" control. Sometimes there seems no rhyme nor reason to my readings but I'm more confident of dealing with hypos or being hyper too. You will be too before you know it.
Good luck.
