Your approach, i.e. avoid medication for as long as possible, is a common one and makes sense.
The issue is of course that you have an increased risk of cardiovascular events, and if the statins lower that risk then they should be considered.
As someone who in their mid-30’s had the sudden onset of Hypercholesterolemia and who worked with cardiac physicians, I got schooled really quickly, and now have had great results with the statins for over 15 years.
With that said, the research surrounding statin usage is pretty strong, however Type 1 diabetics are a special case, with less overall research being completed. Were it me, I would tell my younger self to see if the medication helps rather than fight it. If it doesn’t work for you, then you will feel ok quitting.
