I haven't been feeling well but a couple of weeks ago I fixed up an evening with a friend - she is due to come to my house for the evening tomorrow. For various reasons (possibly depression) I really don't want her to come. I just don't want to see anyone at the moment, I don't feel up to socislising and would rather sleep.
I have cancelled a visit from her in the past when I've felt ill. Will it appear rude if I cancel again? I feel guilty about letting her down at short notice.
If I do cancel what can I say? I can't say 'I'm depressed' can I?
