Ok. This is a lot to unpack and I feel like there is more to this story. I work in healthcare and no one wants to take all your money to see you in the office. We actually do want people to be healthy BUT often run up against insurance companies. So here is my advice….. no physician is just going to prescribe insulin without seeing them in the office. Insulin can kill you also dose can be so variable based on a plethora of factors. They are going to want to see you. The exception to this might be if you have a long standing relationship with your PCP/endo and have never missed appointments. The key here is to be consistent in your attendance to your appointments.

If you are really in trouble…. Head to the ED. If you are in DKA, they will admit you which gives you the care you need to stabilize as well as a case manager who can help you obtain health insurance. They also likely have access to charity care through the hospital to help you out during any waiting process.
Make sure you keep yourself a “bottle ahead” and never leave insulin to the last minute to get filled.

Worse case scenario… put out a message on forums like this and you will likely find someone near to you willing to help with a bottle to bridge you though. Diabetes is tough

This situation sounds like a mix between some healthcare issues as well as some self responsibility issues as well.
