Do u think u r useless?

Hi! It is so long I don't add a new post. I have been busy with my exam lately and they will be two exam in August and September. Then, I will take the PMR test :'(
Do you think you are the 1 who is useless than anybody? That’s WRONG if you just see other people good point but don’t see yourself. That’s no something that unfair in the world. God create us with same love. God give us different ability, so why we always hope that we have other people’s ability but no use ourselves? I have a sister who is her hand is been burn by boil water and her hand left scar that will never disappear. She always had been caring by parents and family. My mum cry so sad for her painful and that time she only a 10 months baby and my age was near to two. My parents had job to do, so sister and I had been take care under others people. The person that takes care of me is a housewife and she just take care me 1 person. So she can keep an eye with me. But my sister is send to the baby sitter place. There are so many baby and children that have to take care so the accident will happen because they don’t really take care of my sister. Because of the accident, my mother spend her time with my sister is longer than me and a period of time I have been take care by my grandmother of my mother side. That time I don’t really know what things is happen. I just know that my parent was sad at that time. My sister also doesn’t really know what happen. We have enjoyed ourselves in the childhood and nursery after two years old. Until when my sister have been go to primary school, the student are scare of the scar of her hand and some laugh at her and think she is a weird person. No 1 really want to be her friend. She always feels sad in school and always wants to find me and go with me. I am an idiot and I have do wrong thing. I have told her to go away and no to disturb me with friend. I am such a silly. I don’t know other people will think her like that. She has been sad for a year but she pretends happy after school. Until she is standard 2 some really kind person has want to become her friend and become cheerful. Other students don’t feel weird again and become her friend. I should happy for her but I am also jealous of her friendship. And one day I have talked that jealous of me to her and she reply me that she is jealous of my hand and she tell me the things that happen in standard 1. I am surprise and feel shame of myself. Why I didn’t notice and jealous of her. I have something that she doesn’t have and she also has something I don’t have. We are fair. From that times, I know jealous is a silly and childless thing. We should think more positively, accept and like ourselves. And know, I love myself and my sister very much. I think I will going to cry if she marry in the future because she is such a lovely sister….
