When I was younger I would have a headache everyday after school. It doesn't happen so much anymore unless I talk to someone that is in emotional turmoil or if the person is really negative.
I have fibromyalgia. But I find it is better when I protect myself against people and places that trigger me. Places that there are large crowds and or aggressive/angry people can make the widespread pain worse. I also get chronic fatigue when I have to deal with a lot of other peoples stress. Maybe this is like what you are going through?. Be gentle with yourself x
