I'm big on psychology and philosophy as well. Very fun to ponder and experiment with new perceptions.
The end of my understanding of philosophy did end in a narcissistic existentially nihilistic POV, though my narcissism does extend helping others and is of course my only reason for keeping my curiosity and interests alive. My early transitions were getting rid of my subconscious fear of death--later, building my self-confidence, and improving my social intelligence which is I'm sure the reasoning for our minds to delve into such deep thought in the first place. My recent posts are just fun tricks I've been playing on my own mind.
I started testing as an INTP, but after all this psychological work I did on myself, I've ended up transitioning to an ESFP (or so my MBTI test results have shown).
You'll probably develop some pretty thick skin if you stick here long enough, maybe even thick enough to become a salesman one day.
Best of luck and enjoy!
