I am noticing that as I get older (40ish+, sort of), I am becoming more set in my ways - as we all do when we mature - but it is making it difficult for me to accept new concepts and ideas that may help me to recover from my mental illness.

I find I am not so open to "new" things as I once was to different therapies and medications, and find my skepticism rising, but in a different way than what I usually experience through my illness.

I have reached a certain level of acceptance with my illness, yet I worry that, as I get older, that 'certain level' will become, and remain stagnant as this process of being 'more set in one's ways' becomes more prominant in my personality. It is like a giving-in attitude, and since I am borderline with histrionic and narccicistic tendencies, I just know I will become much more stubborn as time goes on. I am already noticing it.

How does one counteract this "natural" narrowing of the mind with the narrowness one already experiences as a result of illness?
