Move.
It sounds like you're living in a toxic environment which is making you sick. Does that fit your experience (is your history of illness - migraines, etc. - concentrated in the time when you've been living in your current apartment)? So find a new place to live. And be careful what you bring - you don't want to bring the toxic stuff with you.
As a trial run, you could try staying someplace else for a week or so to see if you feel better. Bring as little with you as possible (even the clothes you wear should be new/borrowed), and don't go back to your apartment at all during that time.
I am planning to move in about a year's time, to live with my girlfriend who I'm engaged to and live together. I cannot move sooner because to move in with her, I need to apply for a partner visa, and then wait for it to be processed.

An exercise:
Name something that you do not do but should/wish you did/are told you ought, or that you do less than is normally recommended. (For instance, "exercise" or "eat vegetables".)

Edit to add: Kindly stick to the spirit of the exercise; if you have no advice in line with the exercise, this is not the place to offer it. Do not drift into confrontational or abusive demands that people adjust their restrictions to suit your cached suggestion, and do not offer unsolicited other-optimizing.
