My mom called me a bitch.

I’m 17 and I’ve been my mom only child for 16 years. I’ve been there with her when she was dating men and men who abused her or hurt her or cheated on her and never left her side. She always wanted another child and she got pregnant when I was 15 and had her baby at 16. My brother is 1 years old and absolutely adores her. But heres the problem, now tht someone actually wants to love her and be on her (my brother) she gets annoyed and will make him cry for her. He wanted her really badly and he hasn’t seen her in 13 hours. She purposely was hiding behind a door and teasing him to make him cry for her. Then she takes a longggg shower and dries off slowly to make him cry louder. My stepdad and me are getting frustrated bc most moms will try to b faster so tht they can b affectionate and love their baby. She’s been like this all her life, cold to her children that she “loves so much” and kisses the guy she’s with (who always cheats on her) butts. I’ve been watching him most of the day and I got frustrated and I said mom please get him he’s crying. She says “shut the fuck up.” I say “no you need to take him, idky u like to act this way.” Then she was like “I’m done helping you, no more prom stuff no nothing.” Then my stepdad closes the door n my face even thought he was venting to me about her. Then I say “that’s bad parenting, idky u act like that as a mother.” Then she called me a “bitcch.” It sucks bc I turn 18 in a month and I thought at this time we’d b done with each other but sadly we’re not because she wants me to go to a community college by her. And I’m not allowed to have a job or I’ll get in trouble so I’m dependent on her for money for my prom stuff....
