Sensitivity 

Sensir = Latin 'to feel'

I feel more.

I see so much beauty in life. I walk in nature and I find myself struck in awe by the magnificence of a silver web delicately spun amongst crimson brambles, or of tall, gnarly and intertwining trees, or of the gentle and soothing rustle of a silver birch as it's leaves dance in the sunlight like golden medallions.

To be so sensitive makes life wonderful in many ways. I can draw detailed images simply from my mind, I can learn languages quickly and easily, I can sense the needs of others as if they had spoken them aloud, I can read micro facial expressions, I can play music with acuity and emotion, I can strongly feel the signals from my body and so I feel more incentive to live a healthy lifestyle, I can soothe and comfort people, I deeply moved by art and music on a visceral level, I can use my vivid imagination to find creative solutions to complex problems - including my own.

But in order to feel this and have these wonderful abilities, I have less of a filter. I have heightened senses. The same senses that detect and feel beauty in the minutia of the world around me, are the senses that feel exposed and overwhelmed in the face of the modern world.
I have a lower threshold for feeling nervous system stress. Sometimes it feels like my nerves are raw and exposed. I feel very strong and intense emotions, am easily overhwelmed.

In an ancient tribe, my role would have likely that of a shaman healer.  In the society I know, this role is trivialised.
