Paint sucks - even putting the boot down on it with a top heavy bike can be a scare stopping.
Try testing your traction by braking hard in the wet in the parking lot.
Part of the issue is your bike is light and narrow tires so not much of a patch.
I like Metzler's for wet traction and the profile.
You simply don't want to be on edge on city streets....taking it easy gets you home with least stress and even the best riders get surprised.
We'd done dirt all day and the worst scare was on pavement ....a little patch of sand on a short bridge that was part of a turn.
Lost the front end last year but kept it up as it grabbed traction.
Buddy who is serious dirt distance rider and used to race 4wd at 200 kph lost it in the exact same place this year. Innocent looking bit of cement over a small stream and the dip collects loose sand.
Just ride - the confidence will return but you now know WHEN to be cautious and also that a low side is not the end of the world.
I was happy falling off in the dirt last year on a muddy hill as I'd not dropped a bike in decades since I had my trialers.
Armour worked and I was no worse for wear...learned I could still ride out with a clutch.
If you want to improve your "awkward situation" skills.....take some dirt riding courses.
