Continuous Glucose Monitor

I am diabetic and I have recently become fully insulin dependent as I am no longer responding to oral medications. Insulin has already made a huge difference in my life--but because of that adjustment, as well as a new job where I am more active, I've been experiencing quite a few lows. My lows always come back up, but not always easily or quickly. 

Because of this, my doctor is prescribing a continuous glucose monitor so I can closely monitor my sugars. It will alert me when I begin to get too low. Even with insurance, I am looking at $250 to just get everything started. But the monitor will allow me to stay healthy, keep track of my blood sugars and give myself and my family peace of mind that I’ll be alerted early to my low blood sugars. What I'm asking for is as follows: 

$63.12 for the first pack of sensors 
$97 for the Dexcom G6 for the receiver
$89 for the Dexcome G6 transmitter ($250 just to get started.)

Anything else raised toward my goal will go toward new sensors, which usually only last 10 days. Each pack only comes with three. Also, once every three months, the transmitter must be replaced. Thank you so much for any help you can give!
