My stepmother was a lot like that with my siblings and now she's upset the ones that grew up and moved out want nothing to do with her. On top of that they're pretty messed up. One became just as much of an abusive control freak and the other became a submissive maid who washes her boyfriends feet. This is more for your mother who reads your stuff, but for you my only advice would be to gtfo as soon as you're legally old enough.
