Welcome to the forum kagome.
I don't know much about
asthma, but I doubt it has much to do with your gallbladder, kidney or fibrocysts.
Cutting hair for migraines? You might start keeping a good diary for that though, as some people have food and chemical intolerances that cause it. http://www.learningtarget.com/nosulfites/index.htm
Low blood pressure on standing up is common in young people, especially women. Have you seen a cardiologist? Ask him if you need aspirin or something for the clotting.
Have you seen someone besides ER docs for the gallbladder?
Vitamin D - how low? Should be 50 to 80. For every 1 unit you are low, add 100 IU to what you already get in vitamin and calcium. You need vitamin K, magnesium and zinc for the D to work. K is mainly in leafy greens.
