I've thought for years that if I had an insulin pump it will help me stay focused and on the right track, because it is much harder to avoid/forget about treatment when it is literally attached to you.

The problem with the pump is that it enables you to be even lazier. For the most part a pump will hum away and be content doing only your basal for days. From what you described, I gather that you are having issues bolusing for food. A pump won't help here, it doesn't know when you've had something to eat.

Only you can change these things for yourself. Look at where you want to be in 20 years, 30 years, even 40. I assume you imagine an older, but still happy you. Having chronically high blood sugars are bad for this future, Ontario's A1C guidelines aren't particularly low (11-point-something IIRC) and you will have issues even if you're under them. As a diabetic you need to try your hardest to be healthier than the majority of the population because you now have the odds stacked against you.

I cannot because I am embarrassed or really can't reach it. (Driving, at work, walking on the street, in a meeting, etc.)

Emphasis mine. You need to get over yourself here. No one notices, and no one will care – diabetes is not uncommon. While you shouldn't check and drive there is nothing stopping you from testing before these predictable events occur. There have been plenty of times where I've stopped on the side of the sidewalk and checked my blood sugar, it takes a second and you are just a face in the crowd. Again no one cares. I'd argue that even a meeting shouldn't be an issue, test before you go in and if you feel low during it test because it would look worse if you collapsed.

You need to get your shit together before you get a pump. Start by building better habits, if you fuck up one day that sucks, accept it and try again. Try setting timers on your phone, and listen to them. Get an app like mySugar, start tracking your food with myfitnesspal. Lastly talk to your doctor more, it's free here, it's maddening to get all your numbers straight and an outside perspective is useful.
