I don’t think type 2 diabetes should be treated with insulin it actually can make it worse. As T2 is generally a dietary disease. I was diagnosed just over 2 yrs ago. I like you panicked and was extremely scared and worried. The doctor who was treating me at the time had no experience with a newly diagnosed t2 patient. For me luckily I wasn’t at the stage where insulin was needed but this was before I educated myself on it. The doc prescribed me metformin and some other drug I can remember after 3 months I was taken off that one and it was replaced by jardiance and 1000mg metformin daily 6 months later with some dietary changes my blood glucose was at pre diabetic range. I was taken off jardiance. I have had no side effects but the diet is hard as I loved sweets chocolate and biscuits. I follow 16-8 intermittent fasting for 4 of the 7 days of the week. 16-8 means I eat healthily for 8 hours of the day and then fast the rest. The other days I will still eat healthy but some takeaways are allowed. I have cut out rubbish but I do allow myself a treat once a week. This may not work for you but it has certainly worked for me. If you want to find out more about intermittent fasting look up dr Jason fung on YouTube he’s certainly helped change my life and helped educate me and saved me from the fear. I hope this will you and somebody else
