So, judging from the “sugar” thing you seem to think you might have developed type 2 diabetes. Do you have any symptoms at all that would support that? It’s very unlikely you’d develop that at the age of 20.

Also, just a note, type 2 is caused by many factors but people are very confused about the “sugar” thing because eating any carbohydrate is the equivalent of sugar. You can view foods like rice, potato or corn as basically sugar, as vegetable starch is just a chain of glucose molecules.
