i personally say do't listen to te above posters (sorry, i love you all but...) being told you're fed up and not depressed isnt helpful. Let's face it, you don't know the poster, what she goes through etc. Maybe she is depressed, but just because she doesnt have te words to express it, doesnt mean it's not true. It can take a lot for someone to acknowledge and reach out.
Of course it may jut be a period of fed upness and you might be right, but it would be better for the OP to make an appt with the GP who will do that scoring test with her and see if she IS actually depressed. There are very few illnesses that can be made worse by physical activity, so if you are able, barry's idea is a good start
