Hack my account

Hello, I need urgent help. It seems my account has been hacked and my email and password have been changed. I've tried to change my password because I forgot it, but I'm not receiving the email, and when I check the website, the email isn't mine. I was able to log in to my Steam account after the hack. My email for this account is [Removed by Support] so you can verify it. Please help me reset my email so I can change my password.
