Losing my mother at my birth and my father at 16
Since you lost your mother at birth, you were still incapable of experiencing the changes that you indicated in your life. Rephrase that particular sentence. It would be better to separate your mother's death during your birth from that of your father at the age of 16. You can only make the claims that you did in that paragraph if you were already old enough to understand the repercussions of what happened to you.
This love, born out of the loss of my mother
Again, you cannot make this claim so easily. You never knew your mother since you were newborn when she died. Her impact on your childhood is insignificant. Stop using that as a reference.

Your writing is choppy. It varies from a motivational letter to a personal statement. Take out all personal statement aspects and focus on the motivating factors alone.
