Is it normal to have mixed feelings about one's parents?

mostly talking about my mum, but i often have mixed feelings about the environment i'm growing up in. i am very grateful for the way my physical needs have been always fulfilled, and me and my mum are fairly close. although at times i feel like she fails to listen to me, judging me before i even get to have my word.
but then i feel guilty because of this thought as the rest she has done for me is everything i could ask for, except the mental support at times.
are these thoughts normal or am i being selfish for expecting more than my needs? comments are more than appreciated
