Katy - that is an excellent description! I am glad that you are singing again.
I am so lucky that no friend or family member is of the "pull yourself together" brigade, and I have made a decision that I will answer kind enquiries about how I am with the honest statement that I am suffering from depression, rather than some banal comment about being a bit tired at the moment.
Responses have been overwhelmingly understanding and caring. And quite a few fellow-sufferers have crept out of the woodwork and been happy to tell their tale, and to encourage a belief that it does pass. The only difficult bit has been a member of my OH's family who lives abroad and will be in UK next week, and wanted to come and stay for 3 days. He says he will look after me and do things to help, but I have had to put him off as I just do not have the energy for consistent socialising for such a long period - the response was to hope I am better soon, but added the barbed comment that he was "sorry you do no think I am able to help." I do not blame him, as he clearly does not understand how it feels, but I will have a few fences to mend when I am feeling better.
I am glad that you had such an understanding boss in the end pompa and thank you and everyone else for encouragement and advice - I'm resting - honest!!
