I tried my best to correct the senteces. You have a little bit confused about your degrees and majors. Did you meant to say "I have a degree in Physics with a major in Chemical Engineering" OR "I have a degree in Chemical Engineering with a major in Physics." OR are you still studying these degrees? In any case, when learning English, it is best to start writing formally. This develops proper sentensing structures and grammar. As such, refrain from using "..." at the end of your sentences. Also "i" is alsways capital. keep it up. Good work.      

Hi, my name is Nurul. Since I was young, I have dreamed of being an engineer. After I finished primary and secondary school, I furthered my study with a diploma and a degree. My diploma major was in physics and my degree major was in chemical engineering. I finished my studies about 2 years ago, and now I am still looking for a job. It is difficult to find a job now because there are many competitors. In my family, I only have an older brother. I'm the youngest. My brother is 29 years old and I'm 27 years old. I love my mom, my dad, and my brother. I also have a cat and a kitten. I like the cat a lot. That's why I like the Hello Kitty cartoon. I stuck the Hello Kitty sticker on my laptop, cell phone, and other stuff that I like.

This is my correction. Let me know if you have any questions.
