Hormones??

Someone please help before I go insane my 2 almost 3 year old is absolutely driving me up the damn wall I really hate to yell or sound mean to her when she really hasn't done anything wrong it makes me feel like she thinks I don't love her but goodness!! I cannot catch a break with her it's always something she just can't listen and she knows exactly what I'm saying to her but still refuses to listen to anything I say but ALWAYS wants to be attached at my hip like come on I love you but I just need some space and quiet time right now I feel terrible but at the same time I feel like I could just be hormonal ADVICE????
