In shambles

I just ruined the most important friendship in my life. It's fucking done, over, gone. All because I cannot seem to realize that people are more then just part of my life apparently. What the fuck is the point if you cannot help but damage the things in your life you give a fuck about? Why do I have to feel like I have to fix everything? Why can't I let go and just leave people alone when they need space? I don't get to be happy because I can't maintain a relationship of any kind with someone I fucking care about because I can't respect the fact that they have their own life.
