You have a personal account. You live in Bulgaria. I have not read the PayPal user agreement on the PayPal website there. But let me give you some advice. "Two people can keep a secret if one of them is dead.
You might want to read the user agreement for PayPal in Bulgaria. There is no instant solution to your problem.
Your reasoning for doing this in the first place is corrupt. But the one you did it for is even more corrupt. It's like when you set up snipers to kill your enemy's soldiers, but he already set up a larger perimeter of snipers to kill all your snipers.
He was one step ahead. He used you, and you let him. It would be difficult to connect him to the pending cases, because 'your' email was used. You sent funds to his email, but that could have been for anything.
I compliment you for telling the truth in your question. That way I can give a pertinent answer. In the USA and Australia, PayPal account login credentials are like underwear. Do not share them.
The problem falls squarely on your shoulders. Unless you can convince the person who was using your email to tell PayPal the truth of what occurred, also called the 'rubber hose' solution, you'll probably be held responsible. All you can do is explain to PayPal, in a brief way, not with every detail, like the alignment of Mars and Jupiter at the time; just the facts, and hope they can examine their computer files, and find a pattern of activity to prove your case, you'll just have to do what PayPal t'ells you.
