Can you encourage her to go to an Al-Anon meeting?
Actually, YOU would benefit from Al-Anon, even if she won't go. Your life is being affected by someone else's drinking, albeit indirectly. Al-Anon can help you learn good boundaries and how to detach from someone else's craziness.
Ultimately, you can't "make" your partner recover any more than someone can "make" her mother recover from her alcoholism. We can't save someone else. But we CAN save ourselves.
Hugs, stick around. Welcome.
