There is a sadness and a grief to losing a friendship, one that leaves a hole in your heart that only time and distance can heal. Perhaps you miss the camaraderie and laughter... the shoulder they had been to cry on. You see things that you would have shared with them before... but then your shoulders droop when you remember you aren't speaking anymore.
That is a hard thing and a sad thing and a grieving thing... but you will heal if you give yourself time.
My best friend said to me, "Accepting that someone doesn't care about you when you care about them so very much is very tough."
I've thought about that a lot. She's right... it is. I think there's a lot of different parts to that -- and I think that one of them is that it shakes up your trust in yourself as well -- because you probably thought that they did.
So when you face that you were wrong about that, what else were you wrong about? What else are you wrong about? If you follow that road too far, you start to doubt that anything you think is right... that anyone you trust is worthy of it. But, really, who you don't trust anymore is you.
And maybe it takes time and distance to grow that back, too.
