What is the saddest message?

1. I can't stand perfunctory, but you perfunctory again and again. I hate waiting, but I waited for you for so long that all my pride was easily crushed by you.

Many people have told me to take care of myself, but no one has ever said that I will take care of you in the future.

It may be a long time before you understand how brave it takes for a stubborn person like me to beg you not to leave me and how hard it takes to drive you out of my life completely.

Sometimes I feel like a psycho, pestering myself and bothering others. Sometimes I accidentally know something, only to find that what I care about is so ridiculous. People say that you don't know how to cherish until you lose it. In fact, the loss after cherishing is more painful than anything else.
