Is it normal to feel like i don't belong?

It's hard to say whether it is normal or not, personally I know how you feel, because I am pretty much the exact same, except I only read non-fiction books, and like to write said, genre.
Except for me it's not a strong feeling of alienation, rather I take enjoyment of being a 'loner' and yes, I do have good, personal friends.
I believe there are more people in the world like this than we'd like to believe so yes it is technically normal, yet I also believe the majority of people in this world are extroverts, and love to socialise and make friends; what then, would be considered normal? to be one or the other, or both at the same time, I often wonder. Is it normal to be neither?

(Don't answer these questions, I was trying to get to the point that humans cannot prove whether being talkative or not is considered normal as a vast majority of people belong to both groups in our current community we call Earth).

As for feeling like you don't belong, this could be many things, depression could be a possibility but I would like to think otherwise, I believe it is because you choose to alienate yourself from others, or perhaps it's because you're making yourself believe that you don't belong because you obviously think a different way to everyone else, or see things that others easily miss...
As in, you're special; I have spent my entire life seeing logic in some things that people find extremely hard to understand, and yet my creativity flows beyond me and my mind, and I usually 'sift' through the cracks of controversial theories to find and understand the truth of something without much stress, so as to say that I am not blinded by the delusions that inhabit the majority of us. Because of these reasons I have often felt different than everyone else, and usually avoid others, and at one stage I felt extremely lonely, often thinking that I shouldn't have been born because of the difference I felt in myself, just like you.

But I also recently found out that I have Aspergers which could explain why I see logic in things that others don't, perhaps this is a similar case with you.

Didn't you hear, the quite ones tend to show true promise to the productivity in this world, whom are truly brilliant beings who offer calm and care. "the quite ones are often the smarter ones".

Maybe you are another one of those aliens inserted into human society for some reason. A sleeper agent perhaps, just awaiting activation when your species attacks this planet.

I am sobbing as I read your post because I feel the same way too. I've been hurt so much that it's starting to effect my mentality on how I view the world. Im afraid someone might notice how deeply scared I am and treat me differently.

Yes:)

I've always felt the same way. I never have and probably never will make friends easily. When I was in school I separated myself from people and never talked. Like you, they thought something was wrong with me, but it's what I was comfortable with.

However, eventually I realized there is a lot more to experience with other people, and there are certain things that are more enjoyable when you can experience them with someone else. It's normal to be an introvert, but I think everyone needs people in their life, or some type of social interaction otherwise it gets hard.

It's not easy, but I think we have to learn how to "let go" a little bit.

I relate to this (:

You should take up squash.?

At the end of the day you gotta do whats comfortable for you within the margin of not being afraid to do anything. I think if you give yourself some time you might come to realize you belong just as much as anybody else.
