Pegasus spyware mail?

Hi, this is my first post in this community.

I got a mail at 1 am this morning, sended from me? It said it was a pegasus spyware installed on my devices. It says hackers will send a video of me ”jerking of to a pornvideo” to all my contacts. Is it a Scan or should i be worried? He says he watched me for 5 months and recorded me.

Help me please
