I wonder if there is any human being who does not want to be recognized as an individual and appreciated for their unique features? For me, I have been very much an individualist in my whole life, I think in part because "being different", "unique" and "special" is feedback I have received from most people in my life in many contexts and types of relationships. Going often as far as saying that I am so idiosyncratic and enigmatic, don't fit common patterns and stereotypes, and so hard to understand accurately. I definitely ran into this with both of my Ts as well and there were times I became angry for those claims to be special, because it came with basically stating they could not help me much. It also made me feel at times that they were lazy, not making true efforts to think outside of the box. And still, I definitely don't like when someone tries to force me into molds that do not fit - my first T tried that a lot and it only led to my feeling grossly misunderstood and him feeling incompetent (but he would not admit it openly). I really doubt anyone enjoys or desires being perceived just like one element in a mass of clones or when people, T or not, project overly simplistic features and explanations onto us. One thing I did not enjoy in therapy though is when the T said he apparently gave me "special treatment", e.g. going over session time more often than not or what I felt was too much self disclosure. I did not like it because it made me feel they were not behaving professionally and I wanted to be treated professionally. But recognizing unique features and trying to understand them in their own context is something I very much desire and even expect from someone who has a decent knowledge about psychology and human nature.

Having said all of the above though, individualism and wanting to be unique can definitely be too much, and this is something I am prone to. There is a term "terminally unique" to describe this tendency, when the person actually denies common things and that we are just as similar as different in many ways, including psychological issues. I think the root of this trend can be many things for different people, e.g. for some not being special to caregivers early in life, choosing the wrong people who are unable to acknowledge individual features, or just having a high dose of creativity. It is not a bad thing at all IMO, but too much can easily lead to self-inflicted isolation.
