I feel like I’m not enjoying motherhood right now

I feel terrible saying this and I just wanted to see if anyone else has felt this way and how you fixed it? When my kids were baby’s I absolutely loved motherhood. Now they are 4 and 3 and I feel like all I do is break up fights and deal with whining all day long! They don’t listen to me at all no matter what parenting style I try. I feel burnt out everyday and I feel like I’m not giving them the best version of me and I feel awful about that.
