I hate normal things

Ok, I just got out of high school a year ago and finished my first year at a community college. I thought no college has done something to me. I can't stand normal things. Here is a list of normal things i can't stand.

1. Srarbucks. I only drink coffee at home or at lesser known or unknown coffee shops

2. Mall stores especially Hot Topic. I used to like going to the mall but now I have urges to shop at unknown stores. I also can't stand HT because so many 13yr olds trying to be goth, emos, and otaku everywhere.

3. Walmart. This I've been told is normal

4. Pop music, and also rock and metal bands that are more popular. I only listen to Pandora and while I still like disturbed and nightwish, I like listening to bands nobody heard of.

5. Bohemian fashion and Maxi skirts. It's ugly, everyone wears it. I dress like a darker version of Fairy Kei and Decora. I never wear boho and have gotten to the point where I want to hit people for wearing it.

Finally 6. Books and movies. It's not that I don't like reading or watching a good movie. But I never got into the Twilight movies, but I dislike the Hunger Games, The Walking Dead, Harry Potter more. I like some popular movies like the Matrix and Alice in Wonderland. I also don't get into dystopian books and movies.

Sorry for long post, but seriously am i going crazy. All of these things are normal and I don't like them. Is this a mental disorder or something?
