I tapered off Xanax and the last dose was Halloween ..4 month taper I guess I should have went longer because for the last 6 months I have been in hell!   The anxiety, heart palpitations, insomnia, morning terrors have morphed into depression.   This is the worst depression.  It's painful and I walk around bawling.     My daughter said this is common in depression.  I don't believe it...there is no way anybody can feel as bad as I do and still be functional.  (I have been to the ER 10 times)!     Does depression feel so palpable?      And so intense?   My life is over.   Noway I can feel like this all day and night.for any longer.
