As you all may or may not know I am quite interested in personality psychology, particularly the Myers-Briggs Type Indicator. As a result I have pretty much typed all of my friends and my immediate family members and I have started to notice a bit of a connection between their personality types and some of their psychological difficulties.
My dad has been diagnosed with severe depression and anxiety and there have been many problems with him in the past. One of the things that happened was he would go through periods of time where he refused to take his medication which would result in him taking on this horrible god complex where he believed that he was better than everyone else and that he did not need his medication. Of course this resulted in us treating him VERY differently and he thought that we had suddenly just stopped loving him. He thought that we were the problem and we were abandoning him and did not care about him. However he did not see that he was the cause of the problem. He is an ISFJ. As far as I have read these types have a problem with making concrete decisions based on a limited amount of information that they take in. They only use their Se in ways that will benefit what their Fi has made a decision on. As a result a situation not unlike my fathers can occur and as a result they can become quite depressed.
So I have this hunch that maybe his depression could in some way be connected to his Myers-Briggs type? This does not in any way mean that all ISFJs are depressed or are more prone to depression but maybe what makes them depressed is connected to their functions dynamic? So that a depressed ISFJ would be depressed about something in a similar fashion?
This is completely just random thought that I am throwing out there, I do not mean to offend anyone and I apologize in advance if I do. But what do you guys think? Do you think that maybe there is a connection between various psychological problems and MBTI types? Just in the way that the function dynamics work and the way the brains of people with these problems work? Let me know in the comments it would be very much appreciated.
