My Mum is lovely. But I avoid telling her how I genuinely feel as she then gets upset and I end up having to comfort her, and reassure her that none of this is her fault etc, etc.
Then I have to put up with her anxiously asking 'How are you feeling?' all the time and usually at inappropriate moments like when my DD can hear.
So I just don't confide in her really. It's not her fault. She's actually an intelligent woman, but she's rather silly and self indulgent. I know she loves me, but it's a rather selfish love.
Mis71Mum, if you can, try and take the fact you had that little burst of productivity yesterday as a very positive sign. Clearly the Citalopram is trying to kick start your mood to improve, but it's still early days. Think of your brain as a battery that has been drained to it dregs, and the Citalopram like the jump leads. Just give them time to nump start your brain again.
You will get better. Hang on in there and keep posting.
