Overcoming my dog fear!

My dog is sick and it needs treatment. Because of it's size and weight, we can't carry him to hospital. So, we called the doctor to come to our house to give my dog a treatment. At first, I am scared of my own dog. But because the doctor need me to hold my dog to get it a injection. (plus my brother and sister aren't at home) So, I need to touch my dog and hold it tight to avoid the doctor getting hurt. Fortunately, my mother able to come back from work and help the doctor to have the injection done. If not, I will dunno what to do.
After the injection, my dog is forced to lay down. The doctor called me to carry my dog to a shaded place.. I was like panic.. I dun even dare to pat him, how to carry him? At last, I stil carry my dog.. And it was really nothing..
After the doctor went home, I tried to be a fan by using some papers to prevent it gets hot. I oso get some help from my cousins. But they helped me a while, then they are gone. (still young) I saw my dog very .... I can't hold my feelings and I cried for I think it is suffering very badly. After a little while of fanning, I need to go out. So, I went out and when I got back, my dog came to me and like wanted me to pat him. I was so happy that it become healthy again! And plus I am not scared to go near it anymore..
