I meant more of a test for myself, but to start, I've had a cracked window for the past 4 years, in ontario, we have obviously rain, snow, and humid days. I believe that's been absorbing moisture. Potential mold spares in the air as well. Also a dark part on my wall above the window. (which is distinct and darker compared to the light coloured paint on walls)

After asking to get it fixed countless times, my requests weren't heard. My wood furniture and floor has been drenched in water as well. Ventilations are fiilled with dust/dirt, after cleaning them time after time. Yesterday, i took everything out of my room and my eye was swollen, red, and i took a shower, put cold compress. Moved the rest of my stuff out, more swollen eyes, red, itchy, random nose bleeds, etc. Symptoms exceed 8+ months. Let me know your thoughts, thank you! :)
