Hi
@AJLang . I'm not one of life's folks who gets down, but I found myself hitting the mental wall a short while after my own Mum passed away. It was utterly wretched and I ended up having a few weeks away from work to recover my inner resources and frankly my joie de vivre. During those few weeks initially I didn't do much, then I just felt a like doing a bit, until I felt ready to re-enter the fray.
I didn't have counselling or anything, but I did a questionnaire, a bit like this one, (
http://www.nhs.uk/Tools/Pages/depression.aspx ), weekly (or so) just to assess, for myself how I was coming along. It helped me accept, initially, that I was still fragile, then to begin to recognise that I was feeling a little bit more myself, and so on.
One of the things that really surprised me during that period were the physical manifestations, reflecting my grief, and in particular the absolute and utter exhaustion.
Be kind to yourself. It's such early days, and things will get better, but working (or whatever your personal coping mechanism has been), isn't always the answer. Frustrating, often straightforward time is.
I hope you feel better soon.
