Feeling stressed any advice

Feeling stressed and need to vent
I am feeling so stressed at the moment and am getting severely depressed. I have been with my partner for 11+ years and have the most amazing 2and a half year old togather who we both very much adore, but the problem is i feel like he is the best dad with her when she is being well behaved but when she is having tantrums (she screams like she is being murdered) he ends up telling me that its my fault she is like this because I don't discipline her enough and he goes on about it for at least a few hours, honestly drives me insane because I do the time out, and try to distract her with something eles but she is very stubborn.
There is other things that are bothering me as Well like he barely ever cleans (mabey once every 6 months) never cooks, refuses to do drop offs and pick ups from daycare. I work part time and with the daycare times changing due to covid i am finding it difficult to ask others for extra support (dropping my daughter of at daycare so I can make it to work on time - partner works away a lot but when he is home he still won't take her) Also i have been working for around a year and am having to take time of regularly due to myself and my daughter always coming down with sicknesses and it is starting to take a toll on my relationship with work I am finding it very difficult to handle taking this much time of this frequently due to when I worked before i had my daughter I never took sick days. I wish i could expect my partner to support me better with everyday things like daycare runs or cook dinner just so i can stress less about the little things. I have also recently had a very early miscarriage which the doctor has put down to possible stress but could also be from other health conditions. I just feel like everything is getting on top of me sorry for the long post I just needed to vent
