I'm late to the party here (I realize this post was made last week), but I think you need to re-frame your view of yourself a bit.

Intelligence is only one quality of a person, and feeling superior to someone else simply because you excel in an area that they do not doesn't make sense. There are plenty of people with average intelligence that are much more artistic, or more selfless, or more motivated than I am, and I (justifiably) view myself as inferior to them in many ways. I may be able to get a higher score on a particular test than others, but those other people may be able to write beautiful music, or they might spend their time volunteering with charities, or they may be working tirelessly to further their career.

If other people bore you, it's not necessarily be because you have higher intelligence than them. You may just interact with particularly boring people, or (more likely) you have difficulty relating to others if their interests are not the same as your interests. For example, a friend of mine is a part of the local indie music scene where I live. I'm personally not a huge fan of the genre, but I find some of the stories he tells about shows he plays absolutely fascinating (and usually pretty funny). I'm a pretty mediocre musician myself, so I'm incredibly envious of his ability to express his emotions through music, and I enjoy his demeanor and outlook on life.

Another example: my wife works at a non-profit that helps low-income youth find employment. While her work may not require a high IQ, I still think she's incredibly smart because of her ability to motivate and improve the lives of the people she works with, and I have a huge respect for her and others that have chosen more selfless careers. Some of the stories she tells me from her experiences at work can be hilarious, and some are heartbreaking. Her not being able to follow a conversation on linear algebra doesn't make her seem any more "boring" to me than her not seeing a particular movie would.

It sounds, to me, like you may have a mild form of [https://en.wikipedia.org/wiki/Asperger_syndrome](Aspergers Syndrome). I would consider talking to a doctor or therapist if you find that your inability to relate to the people around you is causing you to feel particularly depressed.
