I have so many ideas for stories. Every time i come up with a new one i write it down. I have tons that i really like and believe they could become really good stories. It's just every time i try to write i become afraid i'll ruin the ideas i came up with, that i'll write the characters wrong from the shows, or movies i use. I'm scared no one will like them, and my writings bad.
You need to read novels. Lots of novels. Any novels. Notice that they all have perfect spelling, perfect punctuation, perfect composition. Notice where they use one space and where they use two. Notice that every speaker in a dialog gets a new paragraph, and every paragraph is preceded by a blank line. Notice any writing techniques or figures of speech. Take notes so you know where you found what you know. It takes a lot of reading to be a writer.
You don't need a lot of ideas to write stories, you need to be a story teller. Writers don't usually need vocal skills relating to live story telling, but since you are having trouble getting started, that experience might help.
