It's very important... probably the most important thing in my life. It's not as much that I want to state "look at me, I'm unique", since everyone is, but (forced) change in my personal integrity, beliefs and even looks are things I will defend... if needed, violently.
A statement like this makes therapists believe I might have a small portion of narcissism in me. Since it seems I'm overly obsessed with keeping in touch with myself (and to some extent less with the world). In follow up I should mention that as a kid other therapists told me I needed to get more in touch with myself like that and get a bit more "personality". So perhaps one thing lead to another.
But the entire notion of being comfortable with myself the first and quite often only reason why I actually want to wake up and get out of bed. So this might explain why I feel overly hostile if people want me to change. I tried change and that ended me more depressed for prolonged periods. The times I feel best and somewhat functional is when I'm not being interrupted in being "me". (whatever "being me" exactly means; I wont go into discussion on that, since I feel it deteriorates into a philosophical debate on how much you pick up from the outside and which forms your personality, etc.).
I thought about my behaviour and myself... considering my inability to adapt and give in to what other people want, I'm actually not that difficult to deal with. There's a lot of stuff which just happens to be in line of some social norm, which makes it work. It obviously points out why I can get along with some people and why I can't get along with others at all. There's no real middle ground with me I guess.
I once went over this with a therapist, and they told me that considering my stance and behaviour, it's the perfect profile for someone to end up in jail... it just happens that a lot of things I do (or don't do) still fall within social norms. (an example would be, and I touched on it a while ago on this board; I still believe in paying for things. I believe a somewhat fair trade. If I, with my personality didn't care for that, I'd probably ended up on the wrong path, long ago). I asked this therapist if there was something wrong with this... but he pretty much told me "I'm not going to touch that section with you... not even with a really, really long stick". The problem pretty much was... it's "stable" and functions somewhat properly and as such a "don't fix what ain't broke" for a big part. Of course it could be fixed and perfected, but let's face it... no one is perfect, and I think I might have been lucky to run into therapists that shared this sentiment.
