You can't unblock yourself. They have to unblock you by going to your page and hitting "unblock friend" It should be right where it usually says "Block Friend" If they just un-friended you then try re-adding them. If they don't unblock/re-add you they obviously just don't want to be your Facebook friend anymore.
