JumpingJack, I totally get you.
We all affected by others, and this concept has importance in therapy.

For example, last Tuesday I had 3 patients in a row.
The 1st one was very happy and feeling good, after meeting him I felt somewhat energized.
The 3rd patient was angry and anxiety driven, loud and demanding. After session I had feelings of frustration/despair and some fatigue, but after I wrote down notes and worked through what happened, it left me.
We always carry other people's projected energies, and we always project our energies onto them, whether consciously or not.

I sometimes see how I exhaust and overwhelm people when I'm kinda hypomanic, they can't hold this Rush so they reject me in some-sense, I could either be offended by it or see the reason behind.
While this is rarely available for me in Real-Time situations, it is still useful information ^_^

I forgot what I was sayin with all that ...

Anyways, today's is MUCH better than yesterday, since I got myself to sit on my mini-research work and I've found out a lot of useful stuff.
While working on it I noticed the shift in my energy ~ I started very low, reading slowly, writing notes etc.. and ended up with like 10 tabs open in the browser all related to the subject, pens and papers around, and shifting between all and writing the paperwork and it all ended when I realized I need a break because I began thinking how I'm going to implement Carl Jung and secondary traumatization into my work .. and that's just too "BIG" so I stop for now... yeah..
