It seems like each time I take an Enneagram test I get a different answer. First 9w1, then 4w5, now 6w5. I can relate to all three almost equally. The descriptions of 4s do resonate with me more than the others, but after discussing Enneagram with a couple people I'm wondering if that's just because some sources model 4 descriptions after INFJ and INFP profiles (since 4 is supposedly the most common Enneagram type for INFJs and INFPs).
I have struggled with minor anxiety issues (such as insomnia) throughout my life, so maybe I am a 6. But I'm not convinced, and it is frustrating to get a different answer each time I take the test. This definitely isn't as clear-cut as Myers-Briggs typing (in which I score INFJ consistently every time).
I checked out a thick book on Enneagram type from the library hoping to get a definitive answer; I read checklists of 20 questions for each type, and the book said that which ever one I respond yes to 15 or more questions is my type. Well, I responded "yes" to 11-12 questions for 4, 5, 6, and 9. So now I'm more confused than ever. Sighhh.
