Is this an over bite, protusion, or some other dental problem? (photos)

My teeth are defineitly crooked, and I think my mouth is too small for my teeth. But it looks like I almost have a monkey mouth. It's really embarssing. I don't want braces or to have surgery, will consider it if there isn't any other option. I'm interested in Invisalin, if it will work with my condition. Any advice is really apperciated. I have an appointment Friday, but I'm anxious and would like to have an idea with what I'm dealing with. Thank you all! (I counldn't the my pictures to rotate, sorry!)
