As I'm digging deeper into Introverted Feeling, I'm realizing the core of the issue, and I've elaborated on it actually often in these forums. I use Te often to compare my capability and competence to other people. In doing so, I've attached myself to my perceptions of other people's views of me. Introverted Feeling is supposed to allow me to realize my own personal identity that gives me the ability to disregard other people's opinions unless it is necessary for a Te goal.
As I explained in Ventrilo, it's more of that I realized that Si is our dominant function to constantly remind us of what's worked for us personally in the past. Te then takes the information and transforms it into goals. The problem comes when Si gives you goals to pursue that do not align with artificial goals Te has set in the present. This is where Fi comes into play giving us an identity that allows us to recognize the Si goal as more important than the current Te obligations.
As a personal example, Si tells me that I want to spend a great deal of time sitting at home reading Star Wars books or playing computer games. That's what I enjoy, and I want to do that on my own time...only. However, I've told myself that there is something wrong with me if I spend too much time at home, and not enough time out in the world, either socializing, exercising, or working. The perceived bad result is that I'll either get fat, not form meaningful relationships or become incapable of having a high income job. That's where Te has stepped in, minimized my level of personal time, and devoted the majority of my time to failed attempts at exercising and socializing along with A LOT of time spent worrying about college.
The role that introverted feeling plays I'm assuming is that it tells me that I reserve the right to look at the demands from the external world, choose the minimum requirements that I deem necessary to adhere to, and then devote my remaining time to personal interests. It also allows me to stop worrying what other people might perceive of me. It's easier said than done and requires completely changing a mindset while keeping an old mindset. It's like, shifting around a mindset that you want in order to align with the demands from the world.
I'm still working on it.
