Need help with 2 yr old

Ladies, I need some advice. My daughter is 2. 26 months. I also have a 9 month old. I know a lot is for attention, but my two year old has been acting out every day all day. Been going on for a few months. It’s so out of control. She doesn’t talk alot so i think part of it is communication. She hits, bites, throws everything, isn’t interested in playing lately, wants tv but then once it’s on doesn’t want it. It’s total chaos all the time. Idk what to do or what I’m doing wrong. I feel like a complete failure. Every day is insanely hard. I try and take her outside. Take her places. Constant fits and it’s just horrendous. 😭
