I´m losing my confidence.

Hello, 21M here, for a very long time, movie making has been a grand interest of mine. I study movies, the stories they are trying to tell, and I am interested in every aspect of movie making, from screenwriting, through camera and sound all the way to directing. (with everything inbetween). I love how all the details come together to say something grand. And thanks to a few of my favourite directors/artists, I have gotten an ambition to make movies myself. I don´t study film, because I applied too late, so I went to study something else, however, my college does have a movie festival every year. Last year was my first year in college, so with my 2 friends we have decided to join this festival and try and put together a short film. It was hard, mainly because we were very late to the party, but we did it, and surprisingly for us, we have won an award for it for the best picture on the festival (in our category). This has motivated us greatly to go and try again, and I am trying to put together an idea, I have quite a few, but they´re always missing something. And when they are not, I try and put together the first draft, and I can´t, the message isn´t clear, it´s too abstract, it´s too simple, the characters are boring, and usually, I just don´t feel with any of these stories that anyone would be interested in watching it, and would get bored immediately. This has been going on for a few months now, and I am really losing my confidence and feel like I simply lack the creativity, that I´m trying to get something out of me that simply is not there, pulling the wrong stick again. I´ve always loved creative works, I used to play instruments, but I couldn´t write a song I liked, I like movies, but can´t write a story I feel is worth watching.

Am I simply way too deep within my own insecurity and fear combined with the lack of skills, or do I have a point?
