5 year old teenage girl

Isabel • Anything can happen

My daughter is 5 and acts like a total teenager. I've just about had it with the talking back, smart remarks, rude comments, and always fighting with her brother and just simply not listening. I feel like crying because shit man, am I a bad parent for building so much anger towards my own child like she just will not listen to anything I say! My husband says I have to put my foot down which I have or atleast try my best to do so. From putting her on time out, taking toys away, nothing seems to really help. But she gets me so angry. She just does the dumbest things sometimes lol and it irritates me. I know shes a kid but my goodnesss!!! I hate my self for even thinking this way about my own daughter. Ilove her and I want to try to understand her but I just idk. Any help any advice?
