My Mojang account was hacked?

Hello. I have a problem. I tried to log onto Minecraft today, after having a tough problem with a Facebook hack all week and I wanted to go hang out with some friends on there. I thought it was a glitch and that's why I couldn't log on, but I checked on my account to change my password and my email wasn't found. I don't know who did it and I do have the UUID, if that helps. I need help because I really don't want to spend another $30 on it, but I will if I have to. Thank you!
