Glucose is not "poison." You have to have glucose in your bloodstream otherwise you're dead. Too much glucose can certainly be deadly, and without insulin, glucose levels will rise, but the levels you're describing are just not enough to cause any noticeable difference that I'm aware of. In fact, the longer you live with T1D, the LESS SENSITIVE you get to changes/fluctuations in BG levels (hence the development of hypo unawareness).
From all your posts, it sounds like you have serious anxiety related to your diabetes. You need to seek assistance from a mental health professional. Anxiety is a very real medical condition, and you need treatment.
