The only thing I am positive about, is that MS can and does cause General Anxiety Disorders (GAD). I'm not talking about normal, situatinal anxiety, which can be cured by relaxing and thinking happy thoughts.

I did take Copaxone for almost a year and I do remember my anxiety worsened, during that time????

EDIT...I took Valium for awhile, B2U, but you would be much better off with Buspar or Paxil, which areADs, especially geared toward anxiety. Valium and such diasapams are very addicting and just temporary fixes.
