Is it normal to feel disappointed with everyone you meet on some level

Do you mean you're in both college and high school? I was confused about that.

You sound pretty normal to me. Maybe you're reading too much into these peoples' responses. Try hanging out with potheads. They are amazed by physics.

Well I'm not only friends with people who are of similar intellectual level as me as I appreciate other qualities in people besides intelligence. I am friends with most people at my college and work place and there intellectual prowess varies. It's just I get the feelings of isolation when no one else is into the science stuff that I am, even when they take science subjects but completely lose interest outside of the classroom and I just wonder why they are doing a science A-level which will lead onto science university degrees if they can't hold a conversation about science. Anyway my all my IQ tests average out to be 120 and the average deviance is apparently 10 so 110 at the least so I wouldn't consider this a massive difference. Of course I talk about what they like but there's only so much made in Chelsea I can take until I just want to move on. In summary this is less to do with intellectual ability and more like a lacking in interest in science, my tv series and current affairs that I encounter daily.

Do an IQ-test maybe that could give you an "explanation" atleast it did to me. Just remember that everyone can learn you something as long as you are open and got a wide perspective you´ll see what others unconsciously trying to teach you and that judging others by their intellect is a matter of your narrow perspective.

You need to move to a place with more of a college-educated demographic. You would fit in fine where I live. In fact, you'd be nothing special, lol. You might miss being special.

I am sure that there are people that have similar interests as you. I don't think you have looked far enough, or maybe it was the wrong time to talk about those subjects. The things that you are interested about are not that uncommon. But I do understand that people in highschool or people in general like to talk about more frivolous things. I have a deep fascination in cats and other animals, and I remember that I'd talk about them for long periods of times, and my friends would get bored. I learned that not all people appreciated what I did. Another incident, in 8th grade, I would use a larger vocabulary and talk about deep abstract and somewhat depressing topics. No one was interested and they didn't want to hear it. I too felt alone. And they too made fun of me by interjecting sentences with biology words that don't even make sense, calling it "(insert name) language". For example,"Oh, that is very mitochondria of you." or "How very mitosis." It was pretty stupid, but it only lasted for a year. Anyway, I'm just saying that the mocking won't last long, and that you should find people with similar interests, not just from school or work. Also, there is nothing wrong with expanding your interests to something that interests your peers more.

Sooo you'll only have friends if they're on your level, intellectually? I have some dumb ass friends, and let me tell you, they're fucking awesome. You should try talking about things they like instead. I mean hell, you can't be that much higher up than them; you spelled 'here' wrong for Christs sake!

I'm impressed by everyone I meet.

I found that having this conversations you seek hasn't much to do with education and everything to do with curiosity.
I'm not very well educated and I'd talk to you and learn from you about this stuff for hours. I always enjoy a conversation that can go in any direction. I had this sort of conversations with all sorts of people: My scientist brother, a smartass teenager, a kiost owner who spends all his spare time reading about history, etc. The thing these people had in common was wanting to learn and to share knowledge.
I'm sure if you keep talking about the things that interest you, you will find someone who cares eventually.
