What are some good, if there are any refference books for writing short fiction?

[Loser.]

I try to write short stories but they always seem to fall apart, even when I've had them played through my head a million times for three months. Sometimes I lose my tone, sometimes I lose my perspective or my point of view. And more often then not, something comes between me and finishing the story, usually tends to be self-esteem issues though. They all blow, I know they do but it's the only way I know how to express myself without writing word for word how I feel in a journal. I don't really want to read 500 pages on how to use the right words, or grammar, I want something to look in when I need help with a specific thing. Something to help me get my idea's organized and full. I usually don't keep my laptop by my desk when I write, I get too distracted, but if there are any good in-depth sites out there that you know, I'll try them. I mean, this sounds kinda weird, to me, maybe not to other people, but it'd truly be helpful, they don't teach fiction writing really out of elementary school except in small amounts. Something where I can teach myself would be amazing. I'm 14 by the way, Thanks a ton!
