I've known this about myself for quite a while, and would just like to say that... um... it isn't really something that makes someone better than everyone else (before everyone suddenly starts identifying as such, lol). There are pretty severe drawbacks.
Particularly this:
Quoteand can become overwhelmed by large quantities of input
One of my weaknesses is sunlight. I get atrocious headaches in strong sunlight and have to wear sunglasses in all but overcast and night-time conditions.
However, in terms of mental and emotional input, being overloaded is a truly horrible feeling. Like you've had the life literally sucked out of you. At least for me that's how it feels. It amounts to your emotions feeling like they switch off totally and all that's left is an empty, blank feeling of apathy and lethargy.
The solitude thing can also be a burden, a need to completely isolate yourself from everything and everyone sometimes because otherwise you feel a maelstrom of intense feelings, sensations and thought patterns that drown out your own feelings about things. I don't think it's the same thing as empathy, in the metaphysical sense of the word, but it feels pretty darn close sometimes.
To be honest, there are times I wish I did not have to deal with it, and be more... I don't know, normal?
