I've been both fortunate and unfortunate enough to try deleting myself once and removing myself from peoples' lives, only to find out [though a false persona] that most didn't notice and the few who could didn't really care all that much.
Now I'm at a point in my life where a lot of people I thought I knew are turning out the same way. I have no friends, will never be worthy of a relationship, and am becoming a statistic to the Loneliness Epidemic, which is a legitimate thing.
I've literally gotten more love at the bottom of a bottle than I have from people.
These days, your life only means as much as what other people want from it. if they could get more desirable things from someone else, or if you have no way to benefit them, then they could care less about you.
