@newlife1, you don't only end up needing insulin if you don't take advice. As @andyscl, type 1 diabetics will need it from the beginning. With type 2, the tablets encourage your pancreas to make and release insulin. If you lose weight the requirements go down due to body mass. However if the pancreas continues to decline then and produce too little insulin then it'll need to be injected. Yes, this can be due to not controlling blood sugar, but that isnt always the case.
There's much worse things you can have @sega_nintendo. The needles these days are tiny compared to when I first started injections and compared to when my dad started they are minuscule. My lad was diagnosed at 4 years old (he's 9 now) which was a shock as it had been late teens/early 20s for me, my dad, and my uncles. He has coped with it way better than I did at 18 yrs old.
