My latest theory about Se comes from the fact that I am an extremely stress-prone person. Therefore, the amount of abrasiveness that comes from Se - especially ESTps, as opposed to other Se types - creates an immense amount of stress. I used to think that I didn't value Se because I am simply an 'emotional' person, but I now think this is wrong; when I look inside, the 'feelings' I experience because of these people is essentially some really stressed out 'feeling', as opposed to something like a deep feeling of 'empathy.' I just realized this because my life contains a ton of stress, and most of the types I struggle cause me stress in some way.
For instance, Te causes stress because it forces me to be a super-organized, structured 'administrator-esque' type of person - which is stressful because I find that role to be quite difficult.
Ti-PoLR causes stress because they are sometimes not competent and I therefore cannot rely on them, which just increases the lack of peace of mind that I experience.
Fi causes stress because it forces me to be a sort of moral perfectionist which can be overdone and is quite straining on me.
OTOH, Si relieves stress. I in fact started watching nature painting, and started needing the outdoors when my stress levels started to go through the roof.
Fe also relieves stress because it makes me LMAO at their observations, and of course, laughter really helps with stress.
Anyway, that's just my latest theory about how the functions are related to stress. Give whatever input you wish...
