Even though you have been fished or hacked, unless it is someone local (say an ex spouse screwing with you) the people who prosecute crimes locally don't really care, they have knife wielding killers to put behind bars. If it is someone local you need to file a police report with your local police department, as this goes down the ID theft road and if something happens to a bank account you need that report for filing paperwork and getting money bank from illegal withdrawls. Reporting it to the department of justice is a good thing, they will probably take no action, but it all gets databased and reported your info adds to the "This is a real problem" report. In the end these are mostly crime rings located offshore.
Now what to actually do.
First get a clean computer, if yours is compromised then it probably needs to be formatted and have windows re-installed. While this is happening see if you can get a friends laptop for a little while (make sure it is also not compromised and use private browsing or incognito mode and Start changing your passwords. Start with your email accounts and move on to your bank accounts. I would probably stop there, as its just not worth the time to go change every password on every site you use.
