Oh, sweet woman! I totally understand. I look back at my life with my kids and see the same thing. I wasn't a yeller, but my insides were always stressed and I always felt stifled. I know I did my best. I know you are doing your best, too! Learn to give yourself some grace and forgive yourself, however you can manage. Your children deserve a mom who isn't angry with herself. So often, when we carry shame and anger for ourselves, we take that out on our children. I found that to be true for myself. Remember, they are kids once. Messy houses matter less than books read. Do your best to teach them to clean with you, little by little they will do it. I know they are so young. Breathe, try to find some support, and know you are loved!
