I recently got an e-mail, saying my computer has been hacked and asking for BTC, they have a password that I stopped using for important things but I'm still kind of scared. Help

It's a pretty shitty email, and they have and I received it in an e-mail I use mainly to sign up in sketchy places. The password that they used is an old one that I no longer use in my main accounts but I still wonder how they got it. Maybe a site where I registered got hacked? IDK, in the coments I'll put the mail I got. Any help will be greatly apreciated.
