You let me down

You were supposed to care about me,  to be someone I could lean on. You told me to call, that you'd be there for me---to talk, to listen, to support me and help me through this.  But you weren't.  I called.  Messages and texts went unreturned.  I try to remind myself that you're only human, that you just didn't know what to say, that maybe you felt like you couldn't help me, or that it was just too sad.  There's no road map for what to say to someone like me.  The truth is that we didn't even have to talk about my sadness, just talking to you about anything else in the world would have helped.
