no patience!

I thought after pregnancy was over I would finally have some of my patience back and be less irritable by everything. I am 3 pp and I know it takes time but everything my toddler and husband does just irritates me to the point that I need to walk away from them sometimes. During the day I obviously don't get a break I have both kids by myself and recovering from a c section so going out and doing things is a struggle and I'm supposed to be resting myself anyways. My toddler is in her I'm not listening to anything you say phase which she was doing even before baby arrived! I'm already tired from breastfeeding 24/7, lack of sleep, running after her all day and on top of doing everything around the house w absolutely no help! Anyone else go through this? Feeling of no patience W your other kids and irritable? Will I ever feel normal again? I was not like this before this pregnancy!!
