What’s wrong with me??

Some days I get so frustrated and stressed and upset and I think ‘my life would be so much better if I didn’t have kids’ or ‘I wish I could get away from it all’ etc

I have a two year old who I love to death and I would never wanna give him up, my question is, is it normal to feel like that sometimes?? I never say anything to him obviously or to anyone else but I end up crying and feeling super guilty afterwards. His dad doesn’t help out at all and his grandparents on his dads side don’t listen to the schedule I try to keep him on. Idk what to do :(
