Just want to wish you all the best, it's very hard I know. I am on IB for CFS, and each letter gives a review date, as Julie says did the letter you had not give a review date? If it does, and they are contacting you sooner, and the letter is on headed DWP paper, maybe you can query it,as that letter is a legal document you can produce in court. (I have been told this). (although I'm still wondering whether they'll try & 'migrate' me to ESA before my review date)
