Depressing call with Dexcom

TL;DR: I'm stressed and am looking for resources to potentially cut costs month-to-month for supplies.

Hi everyone.

I knew when I turned 26 that things would become a lot more difficult for me and my diabetes. I'm completely financially independent of my parents, and even before I turned 26, the only thing I was helped with was my insurance (which was all I really needed).

Things haven't been too difficult so far--I'm on the Tandem T:slim pump, my novalog is only $100 for a 90 day supply, and my pump supplies are about $100/month. The entire reason I got the t:slim was so I could use Dexcom G6--this was all before I switched my insurance, and even before I switched jobs, so I couldn't plan for costs. I had all the supplies together at one point, and it was awesome, and while the cost was difficult to manage, I made it work. Then I switched my insurance from my parent's, to my own.

Today I had a call with Dexcom because my mom (being the most amazing woman she is) offered to help me with supply costs for the G6. A few things happened prior to this call:

1. The rep who called originally stated my 1 month supply would be $100+.
2. The rep called again and then said it would be $65/month.
3. Today, the rep called and said for a one month supply, I'd be looking at $300+ for transmitters, and for a 6 month supply of sensors, it'd be $500+.

So, needless to say, I will not ask my mom to help with these costs as they're unreasonable. The rep didn't seem to be very organized considering I got three different values from them all within the same month (this month), so I'm considering calling Dexcom again to speak to someone new, but I don't know how much that'll help. They told me about financing, but why would I finance over two months for a one month supply of transmitters? I cannot believe this is my reality, and I'm overwhelmed.

In the grand scheme of things, I'm so grateful for my ability to get pump and insulin supplies at a reasonable cost. My insurance deductible is at $1,500 USD, and I'm only $150 into it. I was told once I meet my deductible, the cost of Dexcom would drop to $65/month, but I'm not sure I'll meet that before the end of the year. I'm concerned for myself as my A1C was at 9.6, even though I've been so much better about checking my blood sugar (I check 4-5 times a day with meals and snacks). My endocrinologist adjusted my pump settings so I get more insulin throughout the day, but now my pump lining is turning orange. I also can't even see any specialists without paying a $50 co-pay, and since I get paid monthly and live in an expensive city (I have no choice due to work), I have a very tight budget.

All in all, I feel like a total mess, and I needed to vent. But, I also wanted to ask if anyone knows of any resources I could look into where I might get to cut costs for Dexcom, or any diabetes supplies for that matter? What are helpful questions you've asked to your insurers, and what have you all done to make the chaos of diabetes a little bit more manageable?

Any support (even emotional) will be greatly appreciated. I'm typically able to let things roll off my shoulders, but today I'm being hit hard. If you've read this far, thanks for reading.
