Advice..

Okay, so tonight around 1ish I was in the shower, and then suddenly I started to feel weak, and nauseous. Out of no where. Then I fell (thankfully my boyfriend was in there with me), instantly losing almost all of both my hearing and seeing. I was in that state, for about 10 minutes. Can someone help me understand this? I feel like this could be toxic shock syndrome, as I do use tampons. Super absorbency. This is kind of urgent. I'm scared.
