Hi, have you ever had your vitamin D blood level checked?  I had a terrible problem with what my doctors believed was anxiety.  Then I was diagnosed with a vitamin D deficiency.  After getting my blood level to ~60 ng/ml, all the anxiety disappeared.  I can't say that all of yours will disappear, but I think that getting your D level checked and getting it to a healthy level (50-80 ng/ml) could really help.  And get your family members who have the disorder to check their levels as well.  Let me know if you have any questions.  Vitamin D is a pro-hormone that is invoved in calcium, magnesium, and phosphorus absorption for proper nerve, bone, and muscle health.  Vitamin D is also involved in regulating 2,000 genes that perform untold numbers of functions in our bodies, including turning other hormones on and off to helping fight cancer cells.  There's lots of vitamin D info on my profile if you're interested.  Hope this helps you.  Take care.
