Am I gonna die or

Just found this in the top corner of my closet in my bedroom. Just been diagnosed with chronic fatigue syndrome and I’m tripping out reading that mold exposure causes basically identical symptoms. Seems to be a little bit along the floor of the closet too. I’m afraid to check elsewhere but I’m sure the attic is full of it since there was water damage here last year. Luckily this is a rental and I’m in the process of buying a new home so I can get out of here, but I’m wondering what type of mold this is and how dangerous it could be?
