I totally identify with the feeling. And the constant thoughts of 'where do I get the confidence even applying'. On the other hand, though there are many people who are more talented, also many less talented, so why not me.
Congrats and good luck!
I also got nothing from Penn, I talked to a POI around November, I believe. I see some people got acceptance or rejection notices. I was basically assuming I got rejected. But time will tell.
I also got an acceptance email from UIUC, I am extremely relieved. It did mention that I will be funded, but nothing about the campus visit. I guess it's because i'm not from the states?
Also got a rejection from Berkeley and that's it for now.
