Do you have a lap-top, when you travel? Magda...I'm just a teacher, not anyone who could really give you advice...but sounds to me like multi personalities. Do you see any doctors on regular basis? Have you tried keeping a diary? That might be helpful to keep track of your missing times. I'd see a doctor when you get home. I posted to you before...remember, I have a son your age. Well, try to take care of yourself.
