Nowhere
Once you have come to the conclusion that there is no goal, no target, no aim in life, and once you have understood the futility of your actions, indeed, the futility of any action, then you have to make a decision if you want to move on. And if you then come to the conclusion that you do, the time has come to find someone to walk with you. Since if you walk this long, meaningless path you should have at least someone to talk to.
