Wants2fly, I really don't know the answers to your questions, I'm sorry.
But I just wanted to say thankyou for mentioning this subject, I have been battling with it since Feb last year which is when I caved in.
How do you get your head around it ? Or is that a silly question, I mean, this aspect of depression makes you unable to get your head round anything

!
After years of believing I was unintelligent, I had 'found'my intelligence. Then this happens and I feel like my cognitive abilities are like mush.
Do you find that you cannot concentrate on more than one thing at a time now ? Women are supposed to be such multi-taskers but this is so different - one very simple thing at a time and not too quickly !
I hope that others here answer your Qs cos they'll be answering mine too. I hope I am not hi-jacking your thread - starting to get a bit paranoid now.....eek !
Hey, lets place bets - who's cog. dis. clears first ! hehehe
Keep on keeping on.....Poppet
