Main Differences Between 4 and 5?

I’m kind of struggling here lol. Throughout my Enneagram journey I’ve constantly flipped-flopped between 4 and 5 and I would really like it to stop. I’ve identified as both and have been typed by others as either or. I’m having a lot of trouble identifying which of the types is more prominent in me because there are many exclusive aspects of both types that I resonate with deeply. This year, I want to finally gain clarity on my official type for growth purposes. Because of that, I wiped my typing slate clean in an attempt to dig deeper and discover more about myself through new lenses. I don’t like uncertainty, though!! Please help!!
