Hie!!! Suffering from very worsened asthma, looking forward to relocation 20 F

So I am from a place where aqi is over the roof.. And I think this might be the only reason for my way worse asthma.(it was controlled earlier..when I used to live in a place with a lot of greenery..going there now is impossible) I'm a female..20.. I wanna know if it's safe to be shifting here.. I'm single and will live alone.so.. Where could I stay? What are the safest places?
