"Friend"

I have a friend who I know little about, but who knows a great deal about me. She'll say "I don't want to talk about myself.". It's amazingly irritating. Also she is there to talk when I'm calm but whenever I get sad or angry (and not nessicarily at her) she says "I don't know what to say.". Let alone when I get really depressed or am raging. She says she's there for me, to support me and all that. But I don't really need support when I'm calm. I need it when I'm sad, angry, depressed, and/or raging. Don't bail on me when I need you and continue to say you're there for me whenever I need you. And don't hide everything from me, haven't I proven how open minded and accepting I am already? I should think so. What could you say that would bother me? Whatever it is, try me. You'll see I've become no less open minded and accepting of no fewer things. So what are you afraid of? After all, you say you trust me more than anyone else.
