Morureseris, I think you should be addressing what is going on with you and why you are loosing sleep and being so upset by this. Missing work and being somewhat obsessive about an answer to something that is outside of your control is not a healthy thing for you to do. What the person did is not as important as what you are doing to yourself over a question that might be unanswerable for you. Please stop focusing on the friend and more on your own reaction. I understand you may care about this person, but complete understanding of the situation is up to the other persons control. My guess is that this little nothing he got excited about was somehow an emotional reaction, and not a logical one. JMHO...but nothing to do
with you and are'nt you reacting rather over-amplified as he/she did by being so upset.
Get some rest would be my thoughts so you can think clearer about this. Hope you feel better very soon. Hugs, bj
