The loss of my family members? Keeps me up at night regularly.
My death? Not one bit, don't even want a funeral. Want to be cremated and scattered in some of my favourite places. Then the few people close to me to go on a massive holiday and just celebrate my life, no one to be upset.
My view on this is probably skewed though as a chronic depressive. I'd say 99% of days since my childhood I've thought about taking my own life. Even when things are going good, my mind tells me to hang myself out of the attic door or take myself off to a field where no one will find me and do myself. Thankfully, I know I'm not normal and snap myself out of it. I find being open about these thoughts with my best mate and my Mrs works for me, I'm a complex personality who those on the outside may see as a high flyer or come to for advice. In reality, I'm one of, if not the most fucked up person I've met.
