Welcome to ThisIsMS, Majickyl.
I have no opinions to offer on CCSVI, my recent interests are in vitamin B12; and (although I know these are not at all the same – I have read that nitrous oxide and many medications can inactivate vitamin B12 in the body's stores– could a buildup of nitrogen in the bloodstream do the same?) I wonder if you have had a serum B12 test. The recommendation is that every patient presenting with neurological symptoms should be tested for B12 deficiency. I encourage you to watch the following video – many of your symptoms seem similar:
"Everything You Want Your Doctor to Know about Vitamin B12"http://www.youtube.com/watch?v=BvEizypoyO0
I highly recommend this 50-minute documentary from the filmmaker Elissa Leonard, featuring Sally Pacholok, RN, BSN & her husband Jeffrey Stuart, D.O. (authors of the book, Could It Be B12? An Epidemic of Misdiagnoses
); Lawrence Solomon, M.D., hematologist with Yale Medical School; Ralph Green, M.D., hematologist at UC Davis; and Donald Jacobsen, PhD, at the Cleveland Clinic (Homocysteine Research Lab).
@1:23 "The neurological manifestations well precede the hematological manifestations."
@1:46 "In 1948 scientists isolated a red crystalline pigment and named it vitamin B12. It is a primordial molecule responsible for the health of all the DNA in all our cells. The Framingham Offspring Study suggests 40% of Americans have suboptimal B12."Signs and Symptoms of B12 Deficiency

Thoughts of Suicide
As for the heart disease connection… High homocysteine levels are associated with heart disease. Low B12 levels elevate the homocysteine!
