KO AND OK

Finally, i have fall in sickness today, will bad flu and spinning head......
I did went to work, but with dizzy condition, i have no choice just to lean on the table and sleep for a while......
May be is because i am really tired since Monday,
May be is because i have too many of matters to worry
May be is because i have used too much energy to solve my question with answers......
And there are a lot of may be,

Just think that illness is not a good situation for me now,
By the way, i have slept for an evening and should be ok right now.......

p/s: i heard your voice yesterday, with flu and cough.... i cant do a anything apart to say take care and rest earlier.
