You don't. Nobody will ever truly understand you to a level that will be sufficient.
You are alone with your feelings anon. Those things that are in your head, those things you like so vehemently and all the interests you wish someone else would share with you are never going to be requited not because of some devious plot against you but because it's unrealistic to expect the fantasy in your imagination to become reality.
You are alone. You will always be alone. You can never stop that feeling.
