Is this normal to feel like I do?

So my partner works full time. 5 days a week 8 hours a day. I'm incredibly proud of him but I feel like I'm digging myself into the ground with no way out. We have a 7 month old daughter together and I never catch a break. My daughter usually sleeps all night but lately is waking once or twice a night due to teething. I'm up all night with her and all day plus all housework, dinner to be ready every night by the time he gets home and appointments almost weekly. I have a few hours of time when my daughter is at daycare but that's usually spent doing this grocery shopping as it's easier to do without her. I've tried telling my partner I need help or a break and I just get "well i work"...I'm currently looking for work just a casual job but he doesn't want me to. When I don't do things around the house or have dinner ready I get in trouble...get called lazy and disgusting but when I do it I get no notice either like if your going to point out when I don't do something at least point out when I do...rant over
