I wouldn't believe a word your mom says.

If she has the energy to keep you "crushed", then she has the energy to call 911. Asking for help is HER job. How do you know that this isn't just more attention seeking behaviour designed to keep you stuck? Do not take responsibility for her "illness".

If she does end up in hospital, insist on talking to the doctor so YOU know what the truth is.

Have you considered al-anon ? While your mom may not be an alcoholic, her behaviour is impacting on your life.
