You probably arent ready for this even if I tell you but later on you will realize and internalize the idea that nobody gives a shit about you. People hear that all the time but hearing it and actually internalizing it and taking it into your heart as the truth that it is, is something entirely different. When you finally take in this harsh truth of life you will realize that actually friends are completely meaningless and the very act of seeking friendship is a stage people go through before this breakthrough.
So taking in this fact that you probably arent ready to believe or want to believe, what you do is just continue living your life. They never mattered before, now, or ever will to you because! nobody gives a shit about anyone else
