It sounds like maybe you've moved from Type II to Type I if you're using insulin now? A lot of the insulin manufacturers have prescription assistance programs, as do many of the commercial pharmacies. There's also NeedyMeds or GoodRx if you haven't used those before.

It can be so frustrating to try to get the medications you need when you don't have coverage or much income. That being said, there are usually some ways to find workarounds. It may be helpful to ask a pharmacist or look into one of the assistance programs out there. I wish you luck!
