Thanks for all if the great help. The combination of wisdom, empathy and kindness had helped me through the last few days. Still reeling but managed to focus on my work successfully yesterday and today and the light headed ness was alleviated when I was busy. One symptom I have is finding people at work who are just wasting my time very irritating! Hopefully this too will pass - maybe I will use my own time more effectively. Who knows where this will lead. Thanks again.
