Doesn’t help you now I’m sure, but I’ve found gently banging around the rim or lid of a jar on the concrete outside usually loosens the seal enough to open the jar.
(Outside on concrete because I don’t want to dent anything inside.)

Or just stick a teaspoons other end under the lid, prefferably where the thread begins, lever it up a little and it’ll pop.

Yep, I use the end of a butter knife. You’re fighting the pressure that built up rather than how tight the lid is screwed.
