Can anyone correct this letter? (This is my life story-1)

I already sent it anyway, but I want to know the correct one

Hello Pa___

I’m writing this letter at the Dubai airport, on my way back home.
I went to the UK (England) with my friends last week for a holiday. I
had a great time there. It was my first long hours flight and my first time traveling
abroad by myself since I got hurt from the accident.

At first I was a little bit worried because of my history of illness,
but it was not a problem at all. YAY! :)

You’ve asked about the accident. At very first my the doctors who were
looking after me, they didn’t even know why I had fallen from the 4th
floor of the building where I have lived. I also didn’t know why...
and didn't even realised the fact that I had fallen and hurt a lot until I
saw my wound with my own eyes. That’s because I I’ve fainted when the
accident happened... (2010.11.02.).

So that no one could tell what happeneds at that time, however, with the
building's CCTV(closed-circuit television) and via some medical tests,
thay(doctors) figured out it was my brain thing. It was a Cerebral
Aneurysm or something similar.

One of the blood vessels in my head was swollen and because of that, I
had a spasm and fainted, also unluckily fallen out of the building.
The CCTV showed that I staggered out of my room and walked along the
hallway. At the end of the hallway, there were was fire escape stairs and I
had fallen from there.

At that time my doctor said I was very lucky that I didn’t have a
cerebral haemorrhage. He also told me that the spasm I had was kind of
early signs/symptoms of a cerebral haemorrhage, and many young people around
like 20-30, they don’t know until a brain haemorrhage happens because they’re
young and healthy.

Anyway, at that time, during for 2 weeks after from the accident I was in an
intensive care room and I didn’t realised what happened to yo me. It took
2 weeks until which I really accepted that the facts that my both my legs were are broken
and I was cannot couldn't walk for a long time. I had to undergo major surgery.

Like I told you before, In the hospital, I was very depressed because
I was young but couldn’t walked. At that time it was unsure if that I could can
walk again. Every night I wished and prayed that the whole all situation was is just a
bad dream and if not, I thought, it would be better that I didn't don’t even
wake up at all.

But my parents.. Even though they surely had a very difficult time
deeply but they never showed me and always told me that “we’re happy
just because you’re alive here and that’s all that matters.”

What an amazing story!
