Scammer sent me an email to me from my email address, should I be worried?

Here the email text:

"I have come up with a video exposing the scenes of your passionate masturbation sessions on the left side, whereas on the right side it shows the dirty videos you were watching during that time. .

Trust me, it takes several mouse clicks to distribute this video to your entire email addresses list as well as messenger contacts on your PC or other devices. Additionally, I can easily share all your emails as well as chat history to public too.

I honestly think you would certainly like to abstain from letting that happen. There is a solution for you in this case – perform 1300 USD transfer in Bitcoin equivalent to Bitcoin account of mine (it is really not difficult to do, and you can find online the step-by-step guide, if you have no idea about it).

My bitcoin account details are below as follows (Bitcoin wallet): 1LhnqVQB4GPKSLEctTma3gdkYRQefJv5eB

Once the aforementioned amount gets transferred to my account, I will straight away erase all those kinky videos and vanish from your life completely. Please, settle this payment within 50 hours (2 days). A notification will be sent to me right after this email gets opened, which will trigger the countdown.

Believe me, I am very cautious, professional and never fail. If I get to know about you sharing this message with anyone else, I will right away distribute your private videos to public."

Now, this was found in my work email, my work email is NOT connected to any of my crypto activities. I of course, don't indulge myself while at work or with my work laptop, lol. So any evidence of me enjoying myself is a clear lie because nobody enjoys work anyway. Could someone explain how this email was sent to me from me? Thanks!
