Hi 2 cats, and sorry you are feeling low again, you sound just like me- I have just upped my dose of hrt and had a few weeks of feeling great, and now the awful feelings are back, brought on I think after going to a funeral for my daughters mum-in-law, who died from breast cancer- I was fine on the day but have felt v low and anxious ever since- I think because my daughter is so upset, it has really got to me, it does seem as though it is just lurking beneath the surface all the time and doesn,t take much to set it off again- I have been waking up for the last few mornings with an awful feeling of dread and panic, and can't stop crying. I too had the flu 2 months ago and felt really anxious and depressed with it- it does deplete all your energy I think- really hope that you feel better soonxxx
