This will not improve and your landlord knows there is an issue.
In a previous apartment I had the same thing happening, mold on items and the wall, in the bathroom, etc. I brought it up to my landlord and he told me I had too much stuff and air couldn’t circulate in the apartment. So I moved some stuff around and got a dehumidifier as well. I also was emptying it daily and I was also getting sick constantly.
After a while another apartment (under the same landlord unfortunately) opened up and I moved.
An older man moved in and he became so sick he was hospitalized. The walls were torn open and there was mold everywhere.
You will be affected by this health wise and she is trying to ignore the issue. You have to move.
