People have been coughing and sniffling specifically and only around me for the past 2 years, and it's getting worse/driving me insane. What should I do?

At the beginning of January 2023, I went to college and noticed one girl sniffling sitting next to me, and specifically only when I moved. I thought nothing of it but as I continued going to classes...I noticed more people would do it (only around me). I thought to myself "Are people sniffling because of me? Do I smell bad?". It made me feel very insecure because it happened the whole day, and then continued to happen every single day for my entire semester, and it has intensified to this very day, and I am sick of it because it's driving me insane and making me very angry/depressed.

I began looking at myself first to see what could be wrong with myself or bodily products I use. I switched my ENTIRE body care to unscented because I thought scented products were irritating others but to no avail, people still sniffed when sitting next to me, when I walk past, when i stand up, when i reach for things, and when I talk. I was so anxious and didn't (still don't) understand why this is happening to me. I self-isolated then, and I still in November 2024 self-isolate more.

Since then, the sniffing and coughing progressed to the point, no one can even SIT NEXT TO ME without sniffling when I move and cough when I move and talk. It has made me not want to speak, hide, and runaway from others. I think there is something wrong with me, and doctors have not helped me at all or at least tried to get to the bottom of it. This is affecting me deeply.

To be clear, this never happened to me before 2 years ago...even when COVID was happening...I felt free, I could wear anything I wanted with my body exposed and run, talk, and be super close to others as I please and I wouldn't get a reaction like that from others. The sniffing, sneezing, and coughing. It has made me so severely depressed and anxious that I have anxiety chest pains all the time and my body jumps and trembles when people do it, which is embarrassing and makes me look weak. I don't feel feminine, I don't feel human, I don't feel like I belong on this earth with others. I also feel dirty all the time, no matter when I'm clean or haven't showered it still happens. I never have peace or feel comfortable with myself unless I am alone. I am also scared to wear perfume because I am scared people will cough and sniff because of me. When i smell other girls, they get compliments and people want to be near them, it is never like that for me...even when it used to be. I just want to wear perfume, feel feminine, wear dainty clothes, and be near people. I absolutely love talking to others and showing my personality but ever since this started happening, I have turned into a completely different person. I don't think anyone wants me around and it makes me want to disappear and be someone else.

People used to always say I smelled good and say I was approachable, but I don't feel that way at all now. I get negative glares and people actively move away from me and scratch their nose while talking to me and make weird faces as if I am plaguing them with my existence. I have checked myself SO MANY TIMES, to see if I smelled bad and even asked my friends and family if I smell, and they all said no I smell fine, if i smell fine why are people having this reaction to me? Even people who are near me that actually smell bad, they still don't get that reaction from others. I feel like why in billions of people in the world...this happens to me and its unexplainable? It is making me crazy and mentally ill.

I have noticed this reaction in people more when I sweat, and I anxious sweat because I am scared people will cough, or sniff and it ends up happening anyways. When I raise my under arms is when people cough the most. I check to see if I smell bad all the time, changed so many deodorants and still the same thing. Even when I'm just sitting in a room, and someone comes near me or sits next to me, they cough and sniff...only around me. I feel very uncomfortable wearing open sleeves or my underarms out now because of this, i feel so trapped and disgusting. I feel I can never truly express myself. I don't know what to do and it hurts my heart so much, physically.

I even tested to see if this was normal and happened to others. I watched others interact, talk, and move around the very same people that coughed and sniffed PROGRESSIVELY AND AGGRESSIVELY around me and... nothing. So that is what makes me believe there is specially and truly something wrong with me and my body. It alienates me and makes me feel I not on the same "level" as everyone else, that I don't deserve to be here or have the right to talk or be confident. This is my weakness.

I started a new job and everyone at my job sniffles and coughs when i move/work and I am trying to keep it together, but I can't, I don't know how to make it stop. At my previous job this also happened and has caused me great mental pain when I worked there.

I don't know if it's my blood, sweat, digestive system, or whatever. Btw, I eat extremely healthy with a dash of unhealthy. Even when I drink 8 cups of water, eat fruits and vegetables and even starve sometimes because I am afraid what I'm putting in my body is excreting through my skin....it still happens, even when I smell lovely and put on the prettiest perfume in small amounts, because I don't want to overdo it and have more reactions. This is a very rare thing since this isn't a common phenomenon and it makes me question what did i do to deserve being a germ to others. I believe i am a germ that's invading everyones space. I would be so much more confident if this didn't happen. I wouldn't have dropped out of college if this didn't occur. I wouldn't close myself off and sit as still as possible to avoid this issue.

I don't know what to do, and this is impacting my mental health severely. My self-esteem is 0, confidence is 0, and i am hyper aware and dissociative all the time because of this. I believe there is something wrong in my body, but I don't know where to start or test for. I have thought of getting my digestive system checked, my sweat checked, or anything else. I can't go on if my life will be like this forever, and I know I am not crazy because the people around me that are friends and family notice this but are too embarrassed to say anything or mention it because it sounds bizarre, but it's very real and even more real because I am the only living in it.

What should I do? Any answer/advice or kind words would be appreciated.
