Is it normal that people around me act as if i smell?

Hi, my story begins like this: It was a school week and everything was normal but I stupidly and disgustingly decided not to shower that night when I returned from school. The day after that I skipped showering again. I did this a couple of days until the end of the week. Soon it was already 7 days since I hadn't showered. There was no problem with my smell until the 7th day. That was when I arrived to class, everything seemed fine, but as soon as I sat down kids in the class looked at me and closed their noses. One girl said, "Oh my god! Disgusting." Then I knew I was in deep shit. I realized the mistake I made and i regretted it obviously. This is the outcome of pure laziness and stupidity. After a few classes I couldn't take it anymore. I called my parents telling them that I had to go home to take a shower. I was so embarrassed at myself and ashamed. I couldn't believe where I put myself.

So I got home and I took a shower. I didn't wash my hair though, because I was already used to not washing it for about a week or so. I thought I would just fix my bangs, my mom said it was a bad idea, but she washed my bangs and went over them with the blow dryer. Every week I would blow dry my hair straight and I have the type of hair where it can hold itself as you styled it for quite a while. So I thought it wouldn't be that big of a deal. I am a clean person so I thought that everything would be back to normal. But since it hasn't. The next day I went to school normally. To my surprise, nothing had changed since the day before. People closed their noses when they were around me and had the expression on their face as if they smelled something gross. I thought that I should have washed my hair the day before, and i really should have. So the day was shit. I returned home washed my hair and took a shower.

The following days of going to school were horrible, people closed their noses around me, every time I entered a room people held their noses and complained about the horrible smell. I was confused, and still am, I took really good showers every day but still there was something wrong. I struggled with this, every kid who came next to me would wave their hands against their nose so they wouldn't smell the odor that I didn't understand they were smelling. I put deodorant every day to make sure I was clean, but nothing had changed. It was the worst year of my life you could say. My parents told me that they were just making fun of me and that it wasn't possible that after I showered every day that I would have a smell. And they were partly making fun of me but at the same time they were serious. And I'm not delusional, I know that I smell good but I swear when people were next to me they smell something bad.

I moved to a new city and changed schools about a month or two after that experience. School last year was sort of ok but still everybody around me would complain about a smell that I myself couldn't smell. When people were around me they would close their noses. But it wasn't that bad last year.
Now this year its very different. When I sit with my friends they all complain about a smell. My friend who I thought was my best friend sits next to me and touches her nose all the time as if she smells something bad. Everybody complains about a smell every time I'm around them. Even my teachers hold their noses when I talk to them. You don't understand how my life is a nightmare. It gets bad. When I sit in class people who sit in front of me turn around and look at me while closing their noses. They also look at me close their nose and laugh. They will say that it smells like shit or sweat. I'm not paranoid. I asked my mom if I smelled bad and she said no you smell good.

I am Not a delusional person. I shower every day, put deodorant and a spray of perfume which is a nice scent. I know that I should smell good, but the people at school say differently. Nobody has complained to me face to face. But most people avoid me and walk away. Some are ignoring me sometimes. I'm not the wall, I am a human being. I came to this school clean showering every day, because I learned my lesson from the previous school. But apparently I am still learning my lesson at my current school because people are just dying from the smell that i sincerely can not smell. How is this possible? They smell something I don't? There is no reason for them to be making this up because I didn't physically do anything for them to laugh at me for in the first place. Every time I enter a class room, somebody screams there is such a bad smell. When I stay home, nobody misses me. Please I need some advice.
I believe that I smell good, my family say that I smell good, but body language and people proclaiming that there is a bad odor at school and sometimes public places is telling me other wise. My family don't smell anything bad emitting from me. Though I did visit a friends house of the familly's and the people I was hanging out with there would keep flaring their noses and covering them as if they smelled something bad. They only did this when I was next to them. And I know the difference between having to sneeze or your nose scratching to smelling something bad.
Please, I need some advice and I would really appreciate it. Thanks for reading it means lots x
