There's only one way to find out. Get healthier and see what unfolds. Why do you need an answer now?Talked over some concepts with my therapist and I wanna get your collective two cents about this, I fully acknowledge that this is at a larger scope than an internet forum can truthfully evaluate, yadda yadda. Warning for heavy material.
TLDR; My household has always been abusive and forced me to stay dependent on them financially and physically (having a place to live.) Combine this with extreme social anxiety from bullying, I was a ticking time bomb of grandiose narcissism. I had an extremely tumultuous relationship with an ISFP w/ BPD in my teenage years where that was where I'd fulfill my unhealthy 8 urges. It lasted 6 years on and off. In the end, it became a codependent an anxious-paranoid dynamic where to the point where when explaining how badly I reeled from it in the end, my therapist quested if I thought I had BPD as well.
I won't bullshit and say that a lot of my unhealthy habits of craving external validation and ego boosts are entirely because of abuse and mental illness and therefore, have no real place to consider in my true personality because they do. But I consider them secondary.
I'm currently in a transitional stage of my life where I'm finally in the process of breaking free of my family, recovering from my abuse and reeling in the shitty impulsiveness. I've always thought of myself as having an 8 wing because while I've always been distrusting and paranoid of being taken advantage of in a neurotic 6 way at my very worst, it's because I know the ins and out of power dynamics and a meat-headed sense of "I'm not as weak as those that submit to this" (contradictory, I know.) 7w6 fits me perfectly when I'm in the grip of my circumstances, but I've always felt 7w8 at my core completely separate from my traumas.
What's been on my mind is "is this desire to control I've always had merely retaliatory and will fade away when I'm not in this situation (7w6) or I flourish, no longer having to smother myself to survive and my 8 wing persists because I genuinely value power and strength for myself just as organically as any other 8?"
