HACKED

My Adobe account, Google, personal emails and social media have been hacked.
From what I could find out there is a network infrastructure installed on my own machine with filters, firewall and everything else.
First point: The person who did this had physical access to the equipment. He was the one who took care of the maintenance of my equipment. He became, in a way, an enemy because of a lawsuit that didn't even concern him.
There are several strange things installed like plugins, batches, external settings, deprecated software, like a Photoshop 6 that I found by chance, as well as a media server, device emulator mirroring my phone, and even a support history on the Adobe website, and I didn't open any of the cases.
I need help, what should I do? How to go about proving this, and you see, I'm pretty sure what I'm saying, but I have no idea what I have to do to make the cybercrime police understand the gravity of the case and open an investigation. Help me please...
