Who Am I

To be me is hard work
To be me can be lonely and cold
To have my mind can be confusing, tiring
To try and change is impossible, therefor a feeling of frustration and anger continues to grow.
To except this is who i am brings me tears, why? I don't know.
I am a selfless individual, why do i feel selfish?
Living, feeling guilty for everything i do, Why should i?
Who am i?
Will i ever know?
Someone tell me so.
