Why do you care about such meaningless stuff? You'll be dead for eternity, meaning once you die, you'll travel into the future infinite amount of years. To put this into perspective, it's impossible to even draw a line of how much significance the timeline is starting from big bang up to this day to represent how long you'll be "asleep". Worries that you have right now are worries for the living entities, not the dead. Besides, out of 7 billion people a couple thousands had exactly the same situation as you had. Your situation is nothing special.
My advice is don't suicide at all, try to find happiness even though it may be hard to do so, but if you're planning on leaving, whoever finds out your body shouldn't be your problem anymore.
