Sounds like you are deficient in many areas, but I can say that constant sighing known as air hunger (I assume you mean you feel like you can't get a good breath??) is a symptom of hypothyroidism. I've been hypot for many years and took synthroid until about 2 years ago. Sighing/anxiety never went away until I switched to natural dessicated thyroid. I never knew this myself until reading it on a thyroid facebook page. Also take 50 MG of Lugol'sIodine + protocol.
