Nigthmares About Nose Job. Can You Help?

I didn't like my nose when I was younger. When I was 16 or so I pressed on it really hard to try to straighten it and flatten it. I did this over a period of time as I had OCD. One night after pressing on it something popped and I couldn't breathe through it at all. it feels collapsed. Now I'm 22 and it looks the same on the outside, but I can't breathe through it at all!!! I'm suffering day in and day out. I changed my mind, I like my nose and do not want surgery at all. I just want my old nose back. What should I do? I can't forgive myself for ruining my nose as I NEVER had problems breathing through it before
