"Step mother" from hell

The first meeting

I first meet this women when I was 14 years old. From the moment she saw me she didn't like me. Now the only thing I knew about my dad dating again was that that women would be my step mother. Now as the only interaction with step mothers was watching them get what they deserved in Disney movies after treating the princess like dirt throughout the movie. So thanks to Disney I was afraid of her.Now when she noticed that I was scared of her she got pissed off. She yelled at me saying how dare I even think she was evil. She convinced my dad to ground me from my phone for the rest of the weekend. 

Now I had seen the red flags from this but my dad was happy and I didn't want to ruin his happiness. 

Little did I know that this was going to be the least intense of my interactions with her.
