So-called friends

I feel like Im all alone out here.

All my friends have let me down. My heart is broken and I can't go to any of them about it. For years, Ive been the shoulder to cry on. It didn't matter to me how long they needed me, or how many times they came to me. I was there for them because I loved my friends, and I knew they needed me.

Now when the roles are switched all of them accept for 3 are nowhere to be found. One of my friends actually told me that she was getting annoyed with me sharing my pain with her. Now she doesn't even simply ask "are you ok?".

How am I supposed to feel about that? None of my so called friends seem to care about how Im falling apart inside. None of them seem the slightest bit concerned.
Should I refuse them the next time they try and open up to me?
Should I create a grate distance between me and them?

Its amazing how internal pain can make you really take a long hard look at the external and the people surrounding you. So many of these people who call me brother, friend, homey, etc have shown their true colors. My circle of friends is shrinking more and more every year.

Honestly I dont want to loose anymore friends. But, how do I continue to be the same person I was to them after all this. How do I have an unjudging and patient ear, when the same courtesy wasn't afforded to me? Imagine feeling torn apart inside, and not having a single person to talk to, accept for maybe three people. They are the only ones that care, and you don't want to overload them.
