Introspection: noun, the examination and understanding of ones own mental and emotional processes.

This word has killed me for as long as I can remember.
Being an introvert I'm left with just myself and my thoughts
And, more often than not,
I hate myself for the sins that I've wrought
I'll never be good enough to satisfy myself,
Hell, I don't know if I'm good enough
For anybody else
And all these thoughts and these feelings that I've felt
Have me questioning the cards I was dealt,
And whether I should play at all
Whether I should just fall
Down into a hole and never come back up
Because the world would be better off without me
