I overcame this fear by intentionally trying to be noisy (without creating additional noises than the ones that are actually necessary) and owning to it when I leave the bathroom. I also stare back intently if someone stares at me.

I have a hybrid cooktop. one burner is radiant, the other is induction. this solves all my problems.

I also regularly buy bar keepers friend to clean the pots as stuff stuck outside those pots tend to get fiercely stuck when not using LPG.
