rhino, it took me ages to begin to cope when my mum passed, and just as i was coming to terms with it my dad passed away in my care.
One thing I learned is that time isn't the healer, it's what you do with it. Every time I felt sad, I purposely concentrated on one thing that made me smile about my mum. It took a while, but this week I saw Mothers Day cards for sale in the local shop, and my first reaction was to smile at the cards for all those lovely mums including mine.
Peace be with you.
