Sucess stories

My son is only 3 months old and I have been exclusively pumping. He only gets formula maybe twice a month. I have a pretty decent freezer stash I’m just so scared to use it. I gather as much as I can but don’t want to use it unless I absolutely have to. I’m not back to work yet but I can’t imagine pumping with a job when I already get so stressed pumping a normal day at home. My goal is to exclusively pump for his first year but it seems so far away. Just wanted to hear some success stories that can give me hope
