Plz help save Jessica

My daughter Jessica is 15!!! And was diagnosed with autoimmune thyroid disease in May the doctors put her on meds to try and control it...   they dont work. Her tyroid level should be .5 to a 3 Jessica's level is 275!!!! Her doctors think radiation may need to happen to take her tyroid out.  But she is  need of  a test that her insurance don't cover.   Because the thyroid is so messed up it also effecting her kidneys, her cholesterol and her liver. She is loosing her hair which we all know being 15 that's hard on her! She has days that she ask me why momma why me why am I so sick.
