well... i'm cooked.

the humble water bucket

unless you don't know how to clutch or you don't have one... Then you are cooked for real

Well, you could also do a slime clutch. Or maybe a honey clutch, if it's not too high up. Or a snowbucket clutch. Or you could speed-equip a totem of undying.

but if you don't have any of those?

You could also do a bed clutch if it's at just the right height. You could also do a cobweb clutch. You could also do a lava clutch.

nor those?

You could also do a windcharge clutch. You could also do an iron golem clutch (maybe you could get it to attack you and deal knockback, saving you). You could also do a enchanted mace clutch.

nor those either? just seeing if you will ever run out of options

You could also quit the game just before falling and rejoin to negate the damage on certain versions. You could also get a creeper to expload, yeeting you a little and possibly not killing you, negating the fall damage. You could also grab featherfalling IV boots from a chest-with-boat flying from a happy ghast nearby and put them on. I WILL NEVER RUN OUT OF OPTIONS.

but if i got nothing and am on the latest version, and dont have a single mob near me

Assuming you mean "the lastest version" as glitchless, then you could fall into a nearby lake. Or, you could break your fall on powdered snow (I think). Or, if you are in the end, the ender dragon could knockback attack you to break your fall. Or, you could use /gamemode Creative.

But then you lwk remember you have feather falling 4

oh then you're fine.
