I was Stupid and am needing some advice

I am the biggest idiot out there for not realizing....I was going through a years long lonely spell and tried apps out for about year with no responses and im typically pretty good at spotting scams and id avoided alot( I thought....wrong) well enter this person who messaged me and we message back and forth with normal conversations on Facebook messenger and that eventually over the course of a few days turned into telling each other about things going on in our lives. They tell be they are in Ohio and I am in Texas and long story short it was a back and forth romantics filled few weeks nothing lewd or intimate...all mostly wholesome comments that I as 26yr male have never gotten so I was feeling great and ate everything up happily. A few months down the road closer to 4th of July, they begin starting intimate conversation and eventually asked for a Pic of me and I provided a...full body after I tried to say multiple times I wasnt comfortable with it but I did it anyways. Over the next month it turned deep into constant communication with back and forth long thoughtful conversations. They started to have financial issues ( their story) and I decided to help them out a few times a month sending money through bitcoin ( the flag that I should of noticed then.) I started to want more than texting and I wanted to do video chats and phone calls....well thats when they explain they cant do those because of a broken phone and wanted to have me send them money to get a new one....around this time I was starting to notice that the messages all seemed very chat gpt like and some of the words they would miss spell and such started to throw me off so I decided to do a mini test....I used a ip grabbing type of link for them to click on ( sent them to amazon) and I got something that was in nigeria....this was in October....I couldnt believe i fell for all of it this long so I started to poke at them because if this was a real thing i...didnt want to ruin it....they had good excuses for everything but I then found the real users Instagram of the woman they were posing as and thats when I knew for sure I was dealing with a scammer who knew....everything in my life honestly at that point....I gave push back and they threatened my photo leak....threating all my co workers with their names phone number and even my family... I was shaking....honestly I am thinking about that moment...like a uncontrollable shiver like you were cold. I stalled, said I couldnt afford the phone and how I couldn't believe she'd do this....the stupid thing was I kept contact.....few good mornings they'd send as if everything was in a loving relationship....well I finally had enough of being scared and went no contact and locked down/ made private all my socials and going through a delete me service for data brokers at the beginning of this month. I submitted the hash to that free org so if they did post it that it should get taken down quickly. The thing that freaked me out the most was the Co-workers and bosses, that they threatened to send that photo to....the likelihood i can find as good of a pay job as this as easy as it is....im worried about them sending it to them. They reached out via email last night saying I abandoned them and they gave me 3 days to respond or the thing im not expecting is gonna happen. Thats literally word for word. Im not sure what to do at this moment...I thought I was free from them but I guess not...any suggestions you guys have to handling this im all ears...yes I was dumb...was thinking with the wrong head and I cant believe ive been fooled since march by this.....
