What could this be? Am I in denial or what?
The only thing I can think of is that you're building a psychological wall to resist sharing how you really feel with people around you. You probably subconsciously view it as a battle that needs to be won; to avoid showing weakness.
Do you have a history of having to be the responsible one; the one to be strong when things go wrong?
Sun Tzu: "Show yourself weak when you are strong and strong when you are weak and you will be invincible." Although I don't think the warrior monk was thinking of this as an example. I think it will be ultimately damaging to you.
Can you relate, have you ever noticed something similiar in yourself?
No.
