Is it normal why is my stepdaughter such a bitch

I don't understand the intertube except for this website. So I call my stepdaughter and ask her to find a phone number but I don't know the address or the name of the person. Only his nickname and his old number.He isn't in the phonebook.I also bring up her jury duty notice and how she is probably going to lose her job because her excuse letter is horrible.Her excuse is she has no car and the court is 30 minutes away and she has no way to get there. I pretended to know who put sugar in her gas tank and ruined her car even though I don't. I also want to know why strange numbers keep calling my house. I am sure they are for her. She keeps saying most of them are telemarketers and we are on a do not call list.But they keep calling.
She keeps screaming bloody murder at me like a lunatic to stop calling her and bothering her fiancée at work and not to come by her house to ask her dumb questions like where is the remote and tell her everything she is doing wrong with her life.I also don't understand why she watches psych and foreign soap operas on Netflix. She is also gave me numbers to the senior center and a train group and a group of guys who love trump who hang out at denny's I don't know why she wants me to call them.I think she should be institutionalized but her shrink met me and thinks I am the problem.I don't understand why she is always screaming at me to leave her alone it is very demoralizing and hurtful to her mother.
