You could avoid the Internet. Life would be better. Hacking is EXTREMELY hard to do. Have you PC checked by a professional, and after any evidence is retained, cleaned. Have the tech install protective software. Then, have the tech set your Internet access equipment for greater security. Next, change your password on every site using a different password on each site. UPPER / lower case, numbers, long passwords not in the dictionary. Then, if you must be on the Internet at all, do not go where the bully goes. Choose new screen names. Step away from the keyboard. You could see a lawyer to see if there is any criminal behavior or actionable behavior. Most likely, from what you post, not.
We do not have a client/attorney relationship until you make an appointment, we discuss your case face to face, I accept a retainer, and we explictly agree to enter into representation.
