Is selfishness an outcome of anxiety, or a cause?

Anyone know?

I was reading someone's post about "living in their own head" and having anxiety, which caused them to avoid making social strides and improving, etc. One response to this said it's "the result of having an extremely self-centered worldview," while another said it could also be simple introversion.

For myself, I will admit to being a chronic daydreamer and being self-centered, but I believe this is an outcome of social difficulty... which essentially made me feel as if I was never in control of any situation... which then leads to disconnection, and finally selfishness.

Good question.

Summary - Anxious people are a bit self-centered, but not more than other people. It may feel exaggerated because of anxiety.

I wouldn't say the two are related, anxiety and selfishness, but I'd say they both interact in the mind and magnify each other.
