Worried about polygraph

I have to take a polygraph to verify an interview I had and I fucking lied on the interview about a lot of shit. Lied and said I’ve never done anything illegal. Bitch I pirate stuff all the time. Lied and said I’ve never drunk alcohol underage. Lied and said I don’t have a “secret side” (me supporting LGBTQ+ rights and reading thqt stuff is a secret side, as well as porn bc I live in a conservative family and environment) Also said I have no foreign contacts but I talk to foreigners online all the time. I also mentioned this to my mom but fudged the details bc of stuff she’s disapprove of and I think she knows I’m doing things she dislikes and even worse, thinks I’m into shady things I think I’m screwed at home and for this polygraph
