I am just beside myself.

So, I have a pump (530g minimed) and it's still within warranty. I'm in the process of getting a CGM, and my doctor wants records of my bgs. So I've been going at it hard. Testing 6+ times a day, even. Well, starting Saturday, my BG hasn't been below 200. That's odd for me. I changed my site, changed location thinking it was scared tissue, changed insulin, opened a new bottle of insulin, changed reservoir, tubing, everything. I've fasted. I've adjusted my basal. I've done absolutely everything. I've trouble shooted the pump w/ Medtronic over the phone, I've called my doctor who said "there is nothing we can do for you at this time." And my BG is out of control. For five days now, I've had 13+ units of insulin on board because I'm severely over compensating because insulin is not working. I don't know what to do. My bf suggested I hit up the urgent Care to see if they can put me on an insulin drip to see if it's an extreme case of insulin resistance or if it's my pump malfunctioning. I feel like that's dramatic. I'm just irritated, both because my blood sugar is high and that's a side effect, but also because I'm exhausted and I've tried everything. Help!!!
