just got back from shopping. it was the last thing i needed to be doing but it was a case of having to. I feel totally drained mentally and physically. My head is starting to hurt again. I am sat here in tears....I can't physically do anymore even if i wanted to. There is still so much that needs doing but i really cant even lift myself up enough to even go up the stairs.....WTF is wrong with me??? I feel so damned useless and crap.
