I'm an E/I borderline. I'm always fairly quiet (hence the username, haha), but I become extremely introverted when depressed or in the middle of a bad anxiety cycle. I have documented major depressive episodes and generalized anxiety disorder. Since I've been dealing with mental illness for as long as I remember, I do tend to identify and find comfort in traits and behaviors associated with the illness. I also struggled with an eating disorder. I have to stay in constant therapy in order to prevent relapse because of the familarity in these destructive behaviors. It's really difficult.
I tend to isolate myself more than an extrovert and I am definitely a homebody. I need recharge time. However when I'm at my best mentally, I really do enjoy being around people, helping people, and socializing. I recently took a career change and I am now working in human services and getting my Nursing degree. I have been the happiest & the most social I've ever been since making this huge change in my life.
I've been the most miserable when working jobs not involving people or during periods of time when I'm too busy to see anybody. I speak up way more than my introverted boyfriend and can talk to him for hours - but I can only talk a lot to people I really know well.
My E/I score usually tends to be around 50/50. I strongly identify with both INFJ & ENFJ descriptions. My Fe & Ni are very strong, but I do have a stronger than expected Se & Ti.
