I have been feeling very tired for the past week, I am still sleeping, what could it be?

Hello, for the last week I have been very tired, I sleep not far from 16-20 hours a day when I am not at work. I take several naps a day and I fall asleep at 6pm. Moreover, this is accompanied by night sweats (I already had them, but now they are worse) that wake me up almost every hour. I also have a migraine that started at the same time and won't go away. I had a negative covid test and I am afebrile. I have difficulty doing my chores around the house and at times I feel dizzy. Should I see a doctor about this? And if so do you have any suggestions where to go, my family doctor is not available.
