break down

It's 12:42AM & I just got home from my friend's house where I was editing my documentary that I spent all day from 10:30AM working on. It's not compiling into a movie. At around 11PM we finished editing & it was done & when we went to turn it into a movie it wouldn't work. I'm so upset right now, I'm crying & freaking out & the whole nine yards. I spent my whole day doing this, I didn't do lots of other things that I have to do just so I could get this done & it's not. I don't feel like I was ever taught to use the software & I don't know what I'm supposed to do now. This reminds me of a pottery class I took once & sometimes on the break or when I left I would just cry. I'm out of my comfort zone doing things that I don't know if I have the ability to do & I'm struggling so much. I have no movie to show for the whole day I spent making it. I hate this.
