Hmm, my logical envy seems more directed to ILI types. I would not give up Ni to be logical base so the logical choice for that is ILI.
Going by stories of my childhood I have used Ni by default since I was a toddler. I also used a lot of Fe, when it was necessary, to strengthen my connection to others and fit in more. Without Fe I am not sure if I would have ever formed any friendships at all because I would have been more timid and stayed locked in my own reality that existed independent of others. I just wanted to be left alone for most of my early childhood.
I didn't even want to go outside and play with other children and had to be forced to do so most of the time. I did have fun, usually. once I was forced as long as I could stop and come inside when I wanted. Being forced into social situations upset and made me angry but I finally decided to give everyone what they wanted and then they didn't like it. They would have prefered to have me back the way I was. My personality has grown over the years and there have been many changes. The way I naturally process information has not. When forced to go outside my natural processes it stresses my system and I get cranky/frustrated, stubborn or rebellious.
