Hehehe, comments like that make me suspect SLE
I am a slow and ponderous 'typer' (as Phaedrus is quick to point out). I find it hard to type from descriptions, especially subjective ones. I type my friends from observed behaviour over a long period of time (preferrably), and against types I know well. Especially conflict situations, where people fall back on their preferred elements, are very revealing. I don't think I know anyone of your type from before, so that's why I am grasping a bit
I think you are a sensing type, from what little I have seen you post before. How you like to work out and use your body. You seem very attuned to your body and physical sensations.
You don't seem to be a 'people pleaser' saying things just to keep things smooth and nice. Rather you say you talk straight and to the point and say the truth as you see it often disregarding the other persons feelings, even if you don't like doing so. This points to a thinking type over a more roundabout feeling type. Or an extravert over a reserved introvert.
I don't think I understand your 'fear of people and the physical human life' comment. Afraid in what way? What do you think would happen to you?
Lack of self confidence is not something I think of in association with ST types. Hmm, Fi PoLR? 'Aspiration to humanism and kindness'? Are you saying that Fi is a weak point with you?
I also wonder about if you see yourself as an extravert? Comments like how you draw energy from colours, and physical action, make me think you are extraverted.
I made my IJ suggestion because I thought there might be something to your personal long term goals and the way you go about to achieve them, but my first impression is of an extravert type.
Finally (for now heh) the j/p which I didn't really get a sense of from your text. Are you very organised and set in your daily routines? Personally I am very chaotic (as you can see from the way I approach this thread heh) and dislike routine and chores and doing the same things the same way day after day.
