I know that if you are saying something like . . . "All mothers have children." You don't capitalize mother because we are talking about all mothers. And I also know that when you say . . . . "Mother! I'm scared!" You're using mother as a name, so you do capitalize it. But I get confused when I write . . . . "My (M)mother is the greatest human being ever." Do I capitalize mother or not? Because I am talking about MY specific mother, but I'm not necessarily calling her by the name of Mother.
