Even though Austin Wood's correction is great, I would like to change a little bit.

The health is a luck (<-I couldn't undertand the title either, sorry.)

Last Saturday, I cut my finger and blood spread all over. At the time, I was scared and couldn't stop crying. My colleague drove me to the hopital. The doctor said my wound needed to de sewed. This news really scared me. I didn't want to be sewed, because it 's too painful (<-This, at first hearing, would mean that your whole body would be stitched up! You don't want that to happen, do you? ;p So, as Austin corrected, it will be: I didn't want to get stitches because they're very painful.) . Leaving no choice the doctor finally sewed up the cut as I was crying. After two weeks, I will need to take out the suture; I think that might be more painful so I'm very scared. Fortunately, my friends accompanied me. They helped me do many things like wearing clothes and making my bed, even fed me when I was when I was connected to an IV. Although it was painful and inconvenient, I felt lucky for having many good friends.
At last, I hope everybody will be nice to their body and be careful when you using a knife. You know, it's too inconvenient to do the things just with your left hand.
Good luck.

Great but painful experience! I tried to change some corrections by Austin to other ways of saying them.

So, how are you typing now? With just left hand?! That's weird, right?

Hope your finger gets better soon...^_^

Last Saturday I cut my finger, there was blood everywhere. At the time, I was scared and couldn't help but cry. My colleague drove me to the hopital. The doctor said my wound needed to de sewed. This news really scared me. I didn't want to get stitches because they're very painful. However, there was no choice. Finally, the doctor sewed up my finger while I was crying. After two weeks, I will need to take out the suture, I think that might be very painful and I'm so scared. Fortunately, my friends were with me. They helped me do many things like put on clothes and make my bed, even feed me when I was hanging the saline (I don't understand what you want to say here). Although it was painful and inconvenient, I still felt lucky because I have many good friends.
At last, I hope everybody will be nice to their body and be careful when you are using a knife. You know, it's too inconvenient to do the things just with your left hand.

Wow! What an experience. I'm glad your friends were there to help out.

"unconvenient" is not a word. You should use "inconvenient"
