Immutable Nature

Do we as human beings have an immutable nature that we are born with – a nature that is inherent in our personality and instinctual?

I have been pondering this concept recently and have wondered if it is the source of some, if not all, of my anxiety.
Please, let me give you an example:

Immutable Nature: I have a deep seeded instinct to be socially viable; meaning I love to talk to people and help people. It is in my nature. It is what I instinctually gravitate towards doing.

Confliction of Nurtured Thought: Through the course of my life I have been hurt the most by people. This hurt and pain has caused me a great deal of distrust towards people. When viewed in conjunction with my hypothesized “Immutable Nature,” a problem is easily foreseen.

Since my distrust in people is a condition of the environment I grew up in, it is in direct conflict with the instinct I was born with: to be social. Immutable Nature vs. Nurtured Idealism.

If we view these two separate modes of thought as two separate running programs, would they not be in constant conflict with one another at all times? The only time I feel anxious is when I’m in social situations and situations where people have pressured me into something.

What are all of your thoughts on this – do you believe I am onto something or just reaching?

Perhaps this conflict is the fountain of anxiety.
