I'm not trying to be inflammatory or anything but it seems (and this is from my observations of FPs in the MBTI world) to me that FPs wear their emotional scars like soldiers wear medals and ribbons.
I don't enjoy feeling my emotional turmoil and I don't understand why anyone would enjoy feeling it or wallowing in it. The way I think of it is there's this dark cave with skeletons littered everywhere. There's a foul smell coming from it. There are signs warning you not to go in that cave. You have just as much of a chance of becoming one of those skeletons laying on the ground as emerging victoriously from the cave. If you do emerge from the cave, you're more than likely to be traumatized in some way from what you experienced.
When everything is telling you don't do it, don't go in there, why go there? I know I'm a Fe and what makes good sense to Fe doesn't necessarily make sense to Fi but I don't need to touch fire to know that it burns. I don't need to have scalding burns and blistering skin to fully experience every nook and cranny of pain. I'm far more willing to experience the fullness of positive emotion than negative emotion, but then we get into the whole sweet/sour, dark/light blase blase.
And often to me it seems like people who seek these types of emotional experiences tend to carry a lot of baggage from their journeys. What is wrong with being free and uncluttered and learning vicariously through others? How can you travel down these paths and not expect to pick up anything, which once again is just as likely to be bad mojo as it is to be "good"?
I can see that if you're one of the people goes through the fire and does well, how thr fullness of understanding helps your to reach those in the darkest corners. But it seems to me there are other ways to reach people in the trenches if that is what your goal is. I know people tend to be more receptive to those who have experienced the same things they have, there's greater room for understanding and I agree with that. But for me personally, I don't seek out such things or when they happen to me I don't try to purposely go further down the hole. If things happen to move in that direction then what can you do but move with it, but no purposely delving into negativity for me. I don't view this type of seeking as being "deeper" and in some ways I view it as incredibly foolish.
I guess in MBTI terms, this is extroverted perception at work but sorry I see more effed upness as a result of this than great emotional counselors. I see a lot of hurt people and some overcome and some don't. I don't advocate exploring things like this to their fullest. I think if you sense you're headed in a bad direction, take heed to your senses and go in the opposite direction.
