Freaking out

So I have been freaking out all day. I received a call from my boss this morning stating that a USA on the floor had told her that I have been harassing her,

pulling their hair, tripping them, assulting her, and making do things outside of their scope of practice.

I had to submit a written documentation of my accounts of the accusations for hr purposes. I'm literally 2 weeks from finishing nursing school and have been completely in disbelief.

a little backstory, this USA and I were very friendly for a time, but recently our relationship turned sour. She has spoken to me very rudely lately and the events she spoke to our manager about have been completely misconstrued in their context. For example with tripping, this happened last summer and she had been fooling around trying to trip me so I reciprocated the behavior. Since we haven't been getting along she's gone and made it sound like I'm sexually harassing her all of a sudden, and we have not even worked or spoken with each other in weeks.

Im completely scared this event could impact me getting my license, especially when the allegations have been misconstrued or are complete lies. Especially with today's culture of girl says guy touched them and they all jump on sexual harassment.

Ive worked at my facility a long time, and both the staff and patients really like me. I've never had any issues before. My manager says an investigation will happen which I have no idea entails or will take how long. My biggest thing is we don't have cameras and a lot of stuff is he said she said. At this point I don't even know what I can do.

Not sure if anyone has some advice or has or has ever had an encounter like this.
