Hey Ash,
Don't get hung up about it. I've been riding bikes since I was sixteen, usually heaps of shit with dodgy handling and cornering. I was riding like you until I had a one day track day training course, at the age of 46

I think you are unlikely to increase your confidence by practising on the road, it's too dangerous, you need to be on a track so you don't have to worry about pot holes, white lines, other vehicles, radar traps etc.
We only got taught 5 points, all of which made a huge difference. If I had to pick one technique that would help your situation it would be to look through the corner to where you want to be, and definitely don't look at where you don't want to be

The guy called it "the monster", if you look at the monster you go to the monster, if you look past the monster to where you want to be it's like magic, you just go there
Also, there's no point in looking where you are, it's too late to do anything about that, so just look where you want to be, and you'll get there without even noticing it
