Here's how to solve this:
Shirosaki, you twit, your parents are keeping secrets from you. Your mom isn't actually your mom, she is your aunt. Your real mom died in a horrible car accident when you were just an infant, and your dad, the sleazebag that he is, hooked up with your mom's sister. They don't want you to know about this because they don't know how you'll react. There's more.
Your mom was a covert operative for the Polish intelligence, and she had information about Russian goings on that they don't want anyone to know, and an underground Russian organization has sufficient reason to believe that she passed this information to you from the grave, leaving behind hints, clues in your surroundings, should anything happen to her, so that you will know what the Russians don't want anyone to know. It gets better.
Because you have this secret information, I have been sent as an assassin to eliminate you. Every time you look over your shoulder and ask yourself, "am I being watched?" - yes, you are. Camouflaged as an ordinary passerby or hidden in shadow, I am always there, waiting for the perfect moment to approach you, see what you know, drag you into an abandoned alley and torture you, and whether you tell me what I want to know or not, I'll just keep torturing you. I might approach you as a friend, I might be a bus driver, a clerk at a store you go to more than twice a week, even your ex-girlfriend. I could be anyone. I have planted cameras in your house, I am always watching you. I see you even as you write posts on ProjectEgo. And I even watch you fap. Pervert.
Now, if you ignore or perhaps laugh at this post, kudos, you're just fine. If you go looking for hidden cameras (they're too small for you to see them, sorry) or start thinking that your ex-girlfriend is trying to kill you, you need to get a grip, as I said earlier.
I go back to this, self-diagnosing is a recipe for disaster. It's a catch-22. If you know you're crazy, you're not crazy, as in being crazy, you have to think that you're not crazy. What you have going on is self-projection, you are projecting those issues onto yourself. It happens all the time. Just be glad you didn't pick one of the real nasty ones like BPD. Also, check out a wide array of these articles on Wikipedia, since you seem to rely on it. You'll notice that you have criteria for just about everything there. We all do.
