I keep coming back to this irrationally large fear of leaving people behind.
I continuously wonder who I will see again, and who I will lose forever. I read somewhere in the past that one of the most depressing things to think about is that every time you say goodbye it may be the last time. Not just that a person may die, but also that they may simply move out of your life.
That you may go years without seeing them only because you know that you can see them. Then you reach twenty, thirty, forty years later and look back on the people who were most important to you and realize that they unceremoniously exited your life at a time that you didn’t even realize they were leaving.
