Hello, Tahia =) Here are some corrections. Further, I have tried to rephrese some of your sentences. Happy writing!  =))

Ambulance

AMBULANCE

A horrible thing ever! Before, whenever I used to see saw an ambulance, I would wish to have a ride on that just for fun that I wanna take a ride in an ambulance just for fun. It was so foolish of me until that night occured arrived.
Later One day a situation came up and I had to ride on an ambulance. My father had a stroke and for that, we had to call for an ambulance to take him to the hospital. This situation was dengarous.(The situation was so dangerous , my father had a serious stroke and we had to call for an ambulance to take him to the hospital.) It was my firt time riding on an amubalnce and the whole time I was tense and cried. (The whole time I was in ambulance , I cried and was so tensed. And it was my first ride in an ambulance.) After that night Then I never ever again wished for a riding on an ambulance because you ride on that only when there is a dangerous or serious (you can use either dangerous or serious as both of them sound kind of similiar) situation. Also, an ambulance takes you to no better place but hospital where no one wants to go. Since After that night whenever I see an ambulance on the road, I feel scared and feel so bad looking at the people inside that as I try to imagine what kind of pain they must be going through. It reminds me of that horrible night.
