Computer and phone stolen, Facebook and LinkedIn hacked, email address changed !

Hi,

My case is pretty complicated. My facebook account that I've been using since 2008 has been hacked by someone I know, this person has stolen my phone and my computer and cracked the passwords (he's a computer scientist). I went to the police and reported him, they couldn't do much, they told me that I should hire a lawyer and sue him, but I have no money to do that. Anyways, when the police took him, he gave up and gave me back my devices, everything seemed to be normal, I could log in to all my accounts, I changed all the passwords and thought everything was okay.

However, few days after the incident, using my email address, he changed my LinkedIn and Facebook email addresses and phone numbers without deleting the accounts. I was constantly changing my email password and I don't know how on earth he kept changing it ! It was really weird, I was constantly logging out from other sessions, and had gmail send me a code to my phone if another device tried to log into it, but he just could make it !

I have absolutely tried everything to recover my accounts, nothing worked... I even gave up and decided to create another facebook account with my name (the same as my original account), I added my friends and asked them to report my old account so facebook would delete it... But, only few minutes later he managed to know about it and delete it by reporting it to facebook since he had access to my old facebook and could report any account with the same name (like it's pretending to be someone else). But the weirdest thing, he called me, and told me exactly what I was writing to my friends, like the exact words I typed !

I know that I'm going to sound like a paranoid, but I believe this person is somehow spying on my computer, otherwise how would he know what I was writing, or how could he change my email passwords so fast ! It was like he was reading everything I was typing !

As you can guess, I really don't know much about computers and software, and this freaking psycho would never leave me alone. I know that the whole story is confusing, but I'm really helpless, I don't know what else I can do... I really need help !

I need to protect my computer and phone from hacking, I need to recover my accounts or at least delete them to create new ones with my real names.

Please, help me !

Best regards,
