Growing up sucks

I don’t know if I should be mad or sad or what, but it looks like another friendship of mine is over and I don’t even know why. I have tried everything short of snail mail to try and talk to them and they still wont respond. It just sucks cause now I don’t know who to go to and vent to without having to offer a backstory first, especially on a day like today when all I want to do is vent.
