How Can I Just Sod Off For A Bit?

To be frank I'm having a bit of a mental collapse and I want to disappear. Temporarily mind (say a week or two) not forever.

Say you wanted to go off grid for a bit, without a passport or a driver's license? Where would you go? What would you do?

I've thought about just packing up a tent and such and doing some wild camping somewhere but haven't a clue where. I know that's probably a bit of a romantic view of how that'd turn out and I'd get quite bored rather quickly if I didn't die of exposure first but I don't really give much of a toss right now.

P.s. please don't bother with reddit cares, I already have a therapist. Cheers.
