I always liked to imagine two things for an afterlife.
either 1 : life would "go on" as if i never CTB'd, or anything happened - but everything plays out like a dream! sorta like a comatose state.. and i think theres been a bit of science that backs that up? it was awhile ago. but it would be cool if everything became sunshine and rainbows!
or 2. i would be reincarnated as someone else, maybe then things would be different. but maybe it wouldnt? i dunno. i just dont like the thought of leaving my brother forever ; i guess. even though life is hell i would sacrifice it all just to see him happy.
but realistically it'll most likely be a black void, and im honestly fine with that life is torture, and existing is hell.
