So yesterday I was reading this study which I think you find interesting. I'm a medical student interested in infection diseases, as I was looking for some information I randomly cane across this article. This study stated that there might be an association between toxoplasmose and psychiatric disorders such as schizophrenia. Toxoplasmose can be transmitted by infected cats and causes fever / muscle pain / swollem lymph nodes.

While this doesn't say anything about your specific situation, it might say something about that the possibility between an infection and behaviour.

Now in your case, are your symptoms from an infection or maybe your behaviour/ general feeling causes your symptoms, or another cause

Edit: When you feel bloated it doesn't sound so weird that you are more shy right
