new coworker

I am in a management position in my job that I feel that I don’t deserve, because I am disorganized, and continually make mistakes.

We hired a girl who is my age, slightly less experienced, and she is kicking my ass. She has a better attitude (doesn’t have all my negativity), and I just want to tell my boss that she sound take over, and I should slink away. Self pity much! I feel like its a joke that I am in this position and not her, and I feel embarassed about it. I feel a lot of shame, and it hurts a lot! I know doing models would really help this, but I am just stuck. I feel so judged by other in my office, and I feel angry and closed off and this isn’t my true self. I don’t know what to do.
