Throughout life I have found myself to be a person different from the typical other.
... what is the typical type of a person. I think we all are very different in many ways and at the same time we share many similarities. Therefore this I find as a very tricky sentence. You are comparing yourself with others without a proper definition for them. I feel you should play it safe;
Throughout my life, I found myself different form many of my peers.around when I was a mere three years of age I went to the hospital.
when I was barely three years old, I got hospitalized.I was in the hospital for months, my body becoming weaker slowly through time, the doctors were unaware of what was wrong with me and the only part they knew was of the dramatic decrease in my white blood cell count which dropped severely to a state where death was prominent.
.... I feel this is a bit too long.
I was in hospital for months and months while my condition was deteriorating each day. The doctors were confused with my condition and were helpless in controlling the rapid drop in my white blood cell count and I was almost nearing the death.
