How do u find an otaku girl?

What if being myself is counter-productive. ie. A person feel the very act of existing, annoys other people, so he make it a point having as little interactions with people as humanly possible. At the same time, the very real and growing possibility of him dying alone has terrified him to the point that he is desperate enough to go on dating sites, contradicting who he is, pushing him into a strange limbo where I, long story short, actively undermind my own efforts. What advice would you give this fictional person.

^ My advice to your fictional person is you need to work on changing your internal narrative about yourself. If you are naturally going to assume no one wants to be around you, it usually winds up being a self-fulfilling prophecy where you'll say and act in a manner that will result in people not wanting to be around you either directly or indirectly. Until you change that part of yourself, you're going to be hard pressed to find anything let alone anything that's going to be long-term and meaningful. Admittedly it's far easier said than done, but take small steps in your mind and how you interact with others to beat back against that thought process. Most people won't find you naturally annoying unless you give them a reason to do so.

But you're not a girl You don't count nat
