I think it depends on how well you learn to deal with it. When I was growing up, it was a curse. No one understood me except my mom (also INFJ), so I had few friends in my peer group. Now I consider it a blessing. It opens up so many doors to me now that I know how to put it to use.
And just a point of interest -- you write like an INFJ who has spent a lot of time on the ins and outs of deep grammar (emphasis on the INFJ part -- the lack of deep grammar knowlege isn't a biggy). You write in long sentences, something that I believe to be fairly typical. I actually write in much shorter sentences now than I used to, because I have spent a lot of time perfecting my writing and my teacher suggested that to be an imperfection (I'm not so sure).
Congrats for finding yourself! It's a liberating moment, isn't it?
