Hi Pishte_Kooh
I'm a "pure Canadian", I never changed country (I moved a lot but only inside my province). But still, I cannot relate much to anybody around me. To be honest, I never had real friends. When I was a kid, I had 2-3 "friends" but they were more like acquaintances, as you said. In high school, the first two years I had my "gang", but we never spent time together outside the school. Then I moved at the age 14, and couldn't be able to make new friends, so I spent the rest of my high school mostly alone. Now I'm in college and don't have friends. It is a bit complicated for when there are team works, but I became used to be alone (and it gives me more time to do what i have to do.. lol..) so I don't know if I'd really like to have friends in real life anyways...
Since I'm 8 years old I spend almost all my free time on Internet, which allowed me to make a few "friends" but I don't talk to them anymore, except one. I call him my "best friend", but in reality, he's my only friend. I didn't even saw him in real life yet (everytime we wanted to see each other, there was an impediment and it didn't work). But we share common interests, we support each other and our mentalities are similar. I knew him 4 years ago and now I've realized I never had a friendship which lasted that long.. lol. We are planning to see each other in real life soon, but I still dislike the fact that my only true friend lives in another city.
I can relate to the feeling of lonelyness and alienation, though it is not linked with "immigration". I'd say that in my case, it may be linked with the fact that I'm... just... "different"... and yes, at some points in my life, other kids liked to let me know that I was "different". I've been called "not human" or "a witch" a few times.
I'm a reserved person, too. I can express myself, my thoughts and my feelings more easily in the Internet than in real life. Also,
I simply don't possess the temprament for drinking and loud music, nor do i care about their cultural practices or trends. I'm unable to adjust to their social expectations and i don't find what they enjoy to be enjoyable.
This is also true in my case although I was born here. Birthdays, Christmas, party, alcohol drinking, music, fashion, reality show, or whatever. I don't give a shit. (Which is part of the reasons why I was interested in Islam, I would consider myself as a "ex-almost convert" for that matter.)
So, yea, I think my experience is similar to yours at some points, the immigration put aside.
