I want to preorder an album but it's asking me to verify myself with my security questions but I forgot the answers and when I want to reset them it sends the link to my recovery email and I don't know what it is. How do I change my recovery email?

I've been trying to preorder an album for a while now but I can't because the itunes store is asking me to verify myself with my security questions but I forgot what the answers were and every time I try to reset them it sends the link to my recovery email address but, I don't know what my email is because I made this account like years ago and I really wanna change my recovery email so I can reset my security questions but I don't know how to?
