I fucking hate my sister in law

Anyone else? I swear I have never hated a human so much in my life. And I’m not a hateful person but her... she’s a 2 faced miserable jealous bitch. She’s older than me too so I don’t understand how she’s so immature. She brings up things from 14 fucking years ago and assumes that I’m still like that and acts like I haven’t changed and talks shit about me to my family. And talks shit about my other family members! She always in everyone’s business just so she can gossip and talk shit but makes everyone think she’s so perfect. Can I hire someone to punch her?
