Horrible People😫

I currently am working as a manager. I very much enjoy what I do, however my co-managers & even my GM makes me feel like im not doing well. Today I heard comments "You should know Ms. Manager." & "You should be better then an employee at tasks because your a manager." I try & how else am I going to grow if I dont ask or curios how to do something better. I put in my two weeks & now starting tomorrow & or Tuesday have to get prepared to walk in to a pit of judgment. How should I deal with this situation. Opinions?😞
