I am posting well more than a year since my blackmail/scam incident. It was daunting, I felt stupid, worthless and a shameful. Most of all, the feeling of having been violated was intense. I was alone in an alien city in a far away country. I cried and cried, and listened to some of the podcasts of the admins trolling some scammers. What got me most was the shock, and betrayal and the inability to share it openly with folks I knew. Nevertheless, I actually reported it to the Police, and one Officers was very understanding and spoke comfortingly and that the department is with me even if this case is next to impossible to solve. So folks, speak to someone, family and friends would be best, but someone is better than no one.
It took about 5-7 weeks for me to start getting back to normal. I invested completely into work and worked 14 hours a day including weekends, for almost 3 months. That took away the memories and all suicidal thoughts. Time is a great healer - give it a chance.
There was no video, just a picture - maybe that, coupled with me cutting engagement with the scammers in 45 mins and strictly following all the advice in this site helped.
Now, all I worry about is my personal life and career and making good use of time. I am extra vigilant, and not so naive. I also make sure I think with the right head.
Be positive. This is a small blip in a long life with way bigger challenges.
The only way to move forward is to trust that the video/picture is gone because that is the logical sequence of events if you cut contact with the scammer. Secondly, forgive yourself.
Be strong. You are the result of millions of years of evolution, you'll survive this too.
