Hacked mail

My email [edit: email address removed]  was hacked a while ago. I lost access to it. My Steam account was linked to https://steamcommunity.com/profiles/76561198935771418/ . I'm using a different email address now, but I can't link it to my other Steam account because it's linked to a different email address. I'd like you to either delete my other account with [edit: email address removed]  or unlink my Steam account from that email. Thanks in advance for your help and have a nice day!
