I’m so pissed!

Guys, I have nobody to vent to about this situation. My sister just choked me while I had my 8 month old baby in my hands. She keeps trying to tell me about my life and continue to keep giving me unsolicited advice when she doesn’t have anything going on for herself. I get defensive when she tries to do that, so we always start arguing. I’m so tired of it all. She’s dead to me!
