This is a strangely attention seeking thread considering you keep saying you don’t care and everyone should move on.
The least attention seeking thing to do is -
a) see if the body farm exists and make arrangements,
b) see if you can donate to medical science and make arrangements,
c) look into, and pay for, a direct cremation.
And make your wishes known to someone, or leave them blue tacked to your fridge.
Anything other than these three things is going to cause a lot of attention from various family members, police, council staff, goodness knows who else.
You remind me a bit of the women at a family meal who say ‘ooh I couldn’t, just a half slice of stale bread for me please’ then sit there with a cats bum face when that’s what they get.
