Is something wrong with me or is it everyone else? Also why should I care? Over the past 6-7 years people have gradually started seeing me differently even though I feel like I haven't changed. My age range is 20-25 and I am male. 

The biggest thing probably because of the prevalence is my social activity. I am extremely solitary. In fact because I have struggled to start working a job consistently I may not even leave the house for up to a month or two sometimes and then when I do it is usually something that I have to do. I just don't really care to interact with anyone and most social activities don't interest me. Then according to other people especially my family I am distant and inexpressive most of the time even if I feel fine. People will always ask me if something is wrong because I will not be as excited as them or something but usually nothing is wrong. People also point out that I avoid eye contact and that I pace back and forth. I sometimes laugh at things that people consider upsetting or sad but I have a weird sense of humor. Apparently I also misinterpret people's statements into insults or negative things about me sometimes. 

Sometimes due to video games I will build "friendships" online with people but I end up disappearing from them completely because it becomes too close and too much energy spent. 

I don't think I am depressed because I still enjoy my hobbies and I never really think about any self-harm/suicide. I still find things funny within my range of humor. If I compare myself to someone else I do think I struggle with motivation though. 

Another thing people will do is make comments about me wearing the same clothes all the time. This is true I wear the same couple shirts and shorts/pants all the time but I didn't think it was considered weird until people started telling me (not that I care though). 

Everything I stated above is from what other people tell me and I guess I never seemed to notice them until they were pointed out but I'm still confused on if those traits are "weird". I feel like everyone else are AI or something because of how so many people try to conform to each other. 

I have zero interest in romantic relationships and not much in sexual activities. 

Generally I don't have any similar interests with people except for maybe sports which is more of a small talk thing to me if I have to have a conversation. All of my other interests most people seem to find them weird or unusual. Philosophy and Astronomy being the more normal ones and Cryptozoology, Parapsychology, Ufology, Mythology, Paranormal Phenomena and "conspiracy theories". I do like video games which a lot of people also like. 

I have never had any social media and I never plan to. I hate having my picture taken or even my voice recorded because I don't want it to end up online. I also refuse to talk to the Amazon and Google things. I also pretty consistently feel something watching me from behind my back when I am alone. It feels like if you knew someone was watching you from behind. Sometimes it is so bad that I think someone or something is with me and I will have intense fear to open my bedroom door for example. It only happens when I'm alone and around people I feel everyone constantly staring at me even when they aren't. I don't feel them judging me but that they hate me or something even family. I don't like mirrors because it worries me that I will see whatever I feel behind me especially in the dark. I have frequent nightmares which doesn't help. When I need to go outside for something if there are neighbors I wait until they are gone unless it is very important and sometimes if I see a strange car parked or following me for a while the thought of them spying on me comes to mind. I consider it to be the government or police because I tend to have a lot of beliefs and opinions that would make me a target of the government and deep state. The only other thing that would make sense are extraterrestrials because hardly anyone knows who I am.

The last thing I can think of is that while I have never had a hallucination I do tend to hear things like voices and see things but from a real sound or object. Examples would be hearing whispering from my breathing or the wind or thinking I see a person watching me from outside when it is just a mailbox or shadow. One time there was a wad of shopping bags hanging on my pantry door and it scared me because I thought it was a head. 

Some of my beliefs and opinions people say are delusional but even when I prove it to them they don't budge. I assume they are willfully ignorant. 

Well sorry for writing an essay but at this point because I don't remember how I used to be before high school I feel like if I have changed then maybe I am an entirely different person and then I start to question reality.
