Most of my personality problems result from being too Ni-heavy, so that I'm trying to process the Big Picture, and I am in a constant state of biting off more than I can chew.
One problem comes in trying to find core elements of larger systems, so that I can organize the sea of reality. When this is combined with my anxiety or distortions from experience, it can create an inner landscape of fractures occurring at multiple levels, so when the earthquake of pain is set off, I become broken at the core. This type of inner obsession is like clinging to a tree in a storm and only happens in a state of anxiety. When at peace I take in the vast expanse without judgment and feel enlightened. The levels of emotional pain I feel are something I have hidden most of my life by finding a place to be alone to have a break-down. More recently partners have seen it and are frightened, confused, and overwhelmed by the intensity of it. I end up having to live in fear of it.
A second problem comes from organizing reality along continuums of mutually exclusive poles. In this way you can create an enormous inner concept of reality that is flexible. This is helpful except that I am aware of the extremes of every concept, and once again, when subjected to stress I can become too aware of extremes, rather than a sense of flexible balance. I will consider extremes as greater possibilities than they are. In this way my ability to reason can become distorted and I am aware of some capacity to believe the ridiculous.
A third problem is related to empathy which can become a vice when over-extended. I become hyper-aware of the feelings of those I'm with and can reach an unhealthy point of not being able to identify my needs. The moment someone else walks into a room I have no clue what I want to watch, what I want to eat, or even for certain how I'm feeling. It is a strength at work when compartmentalized and working with just one person at a time, but in my home life I probably need extended periods of isolation where the only thing to feel and think are my own thoughts. This is also not a claim at being virtuous because this ability to diminish self leads to an unconscious anger which can erupt unexpectedly when others exploit the quality. For this reason I need close confidants who are aware of external boundaries, so they can push back against my obliviousness. Also related to this is a penchant for self-loathing.
I've also noticed that when stressed, I will have fluctuating boundaries. I will become intensely private and share nothing, or fall into complete self-exposure. I can keep dysfunctional people at a healthy distance, and then suddenly one randomly breaks through and hurts me. I can go from being suspicious and skeptical about others and then fall into complete trust of someone. I long for inner consistency and it is a core drive in my life, but I have to work very hard to maintain it because I am trying to reconcile every extreme, to discover order in the vast expanse which I cannot ever fully see, but must just extrapolate to make sense of.
So simply put, when subjected to stress I can become emotionally obsessive, depressive, and distorted in my thinking.
There is more, but that's for starters.
