Being an 11 year old child, you're sheltered from the world you are sheltered from the true meaning of life.
Do you mean that you are still 11 years? I don't get why you included this line and what you really meant by that! May be you can reconsider it or re-phrase it to set up a better link with your next idea.
Growing up I can't really say I had avery difficult life although I lived income from a fairly middle class family that did struggle from time to time financially .
... I guess the troubles are financial ones.... it's better if you specify the troubles
Looking back now I remember an incident that changed and shaped my life. Though this happened when I was young I can remember it vividly.
Let's change the order to have a better flow;
However, I still vividly remember one particular incident that happened when I was very young, but was instrumental in shaping my whole character.I was never likeas smart as my two older sisters; I wasn't a strong test taker or a mathematician. I down rightalways struggled in school. However,but my mother was always there to pushkept pushing me to do better. She didn't get a chance to further her education. She had to workworking long hours, raisingto raise three girls all while hiding her sickness.
This is pretty good.... It flows nicely :)
My father who wasis currently deployed at the time would normally be gone for months at a time, but his arrival wasn't a joyful.
.... I wish if you improved the first part of this sentence. It is not clear very clear as to your father was deployed then or now... Some problem with tenses too.... Better re-phrase.
