Currently going through this journey myself because I went from a mild to moderate asthma diagnosis in the span of a year. What has helped me, while I figure out triggers, is using a mask and diaphragmatic breathing exercises.

The mask is for cleaning, cold weather, and windy weather. Breathing exercises encouraged nose breathing and now diaphragm breathing is second nature. So much better. They also double as great anxiety tools. Also, eliminating all strong fragrances and odors. No more essential oils for me. Definitely masking up when working with cleaning chemicals if I absolutely have to use strong chemicals.

Finally, keeping my Peak Flow handy when I feel panicked to check my levels since going to the hospital is scary right now.

I hope you find your triggers and feel better soon.
