Nothing as in my case I'd never want to experience anything no matter what, I just want eternal nothingness, all that comforts me is the thought of being unconscious for all eternity. Existing as a conscious being has only ever caused me suffering and that's why I'd be relieved to not exist, I only wish to not exist as after all I cannot be harmed by the absence of everything, I simply wish for this existence to be permanently forgotten about, I see nothing desirable about suffering in this existence that caused nothing but pain and was always so futile for me in the first place.
