Holy fucking shit. I can't get my stupid fucking pump insertion to stay on, and it's pissing me off.

I have the Medtronic mini med 670g, and i love it. When it's on, which is about 20 percent of the time. I've been diabetic for about 1 year now. But man, I can't do this pump. My mom won't get me adhesive, and I'm just tried of it. What do I do? I don't even know anymore
