It's a long process that doesn't happen over night. You don't go from beta to alpha overnight by snapping your fingers because if that is the case everyone would do it.
It starts with developing the mindset that I love myself and value myself too much to allow anyone to treat me the way she is treating you. This is most likely going to take years for you to develop.
There is no faking it or shortcuts by the time everyone gets to the board. It a process you have to go through. Most people don't make the changes because it's too hard.
That's the catch-22. If you became AMOAFWL you wouldn't want your W back because you would never allow another person to treat you that way.
My advice to you is to get out of living under the same roof ASAP.
