Mediocracy At It's Finest?

So I just posted the last chapter to my story yesterday, and when I logged on today I decided that I would go back and read the story as a whole. I started reading the first chapter and I found myself bored with the story. I couldn't even make it past the third chapter. To me it was horrible, and I don't know if it's just because I wrote it. It seemed less than mediocre. I have gotten a lot of good feedback on it, and people seem to like it, but when I went back and read it I felt embarrassed. Maybe I'm just my worst critic, I don't know. That just kinda ruined the whole day.
