JMB - your post was almost describing me, in fact I have just written a list on paper similar to yours as I am seeing my GP tomorrow.
I too feel like a fraud as I do not feel suicidal or anything near, but just drastically do not feel like myself.
The way you described mood swings was exactly how I have been feeling but have been so irritated I couldnt put it into words - the way you have written it is exactly how I felt, on the "good" days I think I must have been imagining how dark and bad the other days were, but on those horrible days I am in despair. The dark days are becoming more frequent than the good days and are starting to drown me
I think the daily battle of "keeping on top of things" (housework, children, meals, etc, all the simple daily life things) is such a struggle, again just how you described.
Dont look at me - I also keep trying to justify how im feeling or try and validate it against money worries, marital problems (some days I cant stand my DH for no reason??), family, etc. Sometimes it works but then this unsettled feeling creeps back in and I know it isnt REALLY that, argh so frustrating.
Thanks for your post, made a lot of sense and I will take my list to my GP tomorrow, I also have a sinking feeling I will cry and not make any sense, so a written list may be the answer!!
Let us know how you get on with HV and good luck x
