I honestly don’t know why you would have any friends at all and especially not any that would want to be around you given your shitty personality. Not everything is for you. Some things are about bonding and building relationships that matter. Your body will die one day, it will let you down, no matter how hard you push yourself today. The only thing that matters in this life are the people you helped and who helped you. The people who care about you. Those are the ones who will be at your side when your body starts to die. Holding your hand, maybe. Stop being a piece of shit and work our with them. I promise you, for them, it’s not about the workout. It was never about the workout.
