You will need to dace the improtance of getting into a healthy environment. Trying to be healthy while knee depp in a toxic environment will just see you spinning your wheels. Your efforts must be placed on correcting the inner and outer terrain so your body kinfd find coherency and balance.
I suggest you do some emotional energy work such as EFT and TAT and possibly find a good NLP therapist who can help change your metal code so that you will do what is necessary to get well without blocking it. It is all very connected.
"My long-term goal is to move so that I can have a healthy environment. Until then, I am trying to do whatever I can in order to be healthy. " There are no quick fixes. Deep down you know what is needed and must face that. ;-)
