I feel as if I am being watched and see many red falgs in my Macbook Pro- Please help

Here is the other pictures I would like to include and if someone could give me some advice on how to proceed and what steps to take from here. I really appreciate everyone's time and hope you can help!

KiltedTim, I really respect your opinion but after i just posted this I was just locked out of my account when trying to sign in to icloud and to sign in again with my apple ID- which said it didn't match, i restarted my computer and once I tried signing in again it said my account was locked. I am really trying to be an optimistic but at this point I'm not. I hired a private White Hat and he said i definitely have a lot of malware but there was nothing he could do it was so bad i had to get a new laptop. I also switched out my router and got a new IP address. This stems from a company I ordered from over a year ago and basically told me (indirectly) they were going to come after me since an order I placed was either lost in transit or delivery was to thw wrong address etc etc. I won the case because i never received the merchandise. So if you can help me in any way I would love you opinion on how to go about this. Lastly, I will say i saw a document that said "the objective is to breach and hack. I believe this individual.." I tried opening it but when that happened it literally vanished. So i searched the same thing again "Documents" and it was no longer there anymore. The other thing is the picture shown with the writing of using an encrypted email in my notes section under spotlight search. How would/could that even be there if I never wrote it. I hope you can at least see I'm not some overly paranoid individual. These things have happened in the past and now are continuing to happen. Thanks for your reply anyways and wish you the best.
