Let's see... *sits in a high chair, prepares to discuss the facts...* First, the profoundness... sounds like the whispering of a lost soul over the ocean. It feels like something is hopeless, beyond reach, the way you write it, but you have a yearning to discover (or possibly 're'discover) the strength within to love with your whole heart. You said,
"I never seem to fit in,
No matter how I try,
In every thing I do,
I'm left alone to cry"
and that is very passionate, as is the rest of the poem. Second, I meant you were the kindred soul, not we. You said,
"It hurts that my good isn't good enough,
That people don't need me as I need them," ...
... so what does that tell me? People can be so offending at times, and uncaring of others who need them. But you seem to have tried, and found that they act like they don't need you. In the first two lines of the first five stanzas (is that what it's called?), you are the loner, the one who doesn't fit in with the rest of the world. Perhaps you are unique, after all! Have you ever thought of it that way?
Finally, feelings of inadequacy is reflected off human nature. We'll always feel like things will be unfair, but there are some who will have more insight like you have displayed so well in this poem. I call this 'feeling of inadequacy' one word, despair. Even the mightiest of men have fell and wept in defeat before Despair (I use it in those poems I write similar to yours!). For the sword of desolation is long.
Maybe someday I can learn to summarize!
