Yes, that happens to me once in a while, especially when I get too busy with so many other things, work-related and so on. I would not like to post about things which would not be of interest to fellow-myLotters any way.
I get like that sometimes myself. Doesn't it feel horrible? I was feeling that way earlier thats why I got off the computer. Now I am back on but I am starting to feel a little light in the head already. Don't give up, just rest.
