Being a mom it’s hard

I’m a first time mom, my daughter it’s 1 1/2 I love her with all my soul and i can give my life for her, she’s my whole world. But recently I noticed I get really frustrated, of course she’s growing up and has even more energy and wants to play all day, but I’ve been so stressed because of my family, I know they love her so much but seems like they always have something to say. For example, if my daughter wants something that shes not supposed to have it and she starts to cry or getting angry they will look at me and tell me “what did you do to her” when all I am trying it’s to protect her. Sometimes I say “no” to her and they get mad and tell me I can’t even take care properly of her and like I tell you I’ve been so stressed that sometimes I feel bad for yelling at my daughter or seem mad all the time but seriously, them being all day long telling me I don’t have anything good to rise my child it’s making me like this also, they always saying I did something to her when I don’t even spank her, when something it’s wrong I tell her not to do that and she understands. Im really trying and learning but they seem to know everything and make me feel bad for everything I do or decide. Being a mom it’s hard, but I guess all the critics are harder. I feel bad for being mad all day but it’s just to much stress
