I read this thread and realised I needed to check the expiry date on my Xanax! (January 2012). I try not to use it too often, but it is like a safety blanket for me. I rarely go out unless it's local errands or someone else is with me and I only drive locally. I have done the CBT but didn't find it all that helpful to me. I know the vitamin D is a big problem as we get so little sun and the winter days are very, very short. Perhaps I may try a larger dose of it! I rarely get the panic attacks any more though I do still have anxiety problems. Just having to pick up a telephone is very stressful for me, I love email and text messaging!
