Some feelings

I do not know the reason why I often worry about my future,worry about my study and my job in the future.I do not know the situation that other countries,but the people around me often tell me that I must study hard and improve my ability, or you will be given up by society.I want to give a better life to my parent in the future,I have been passed a year of my college life,I did not got anything except my score,I did not do spare works,travel,and fall in love.I hope I can change myself.

Here is my version for your reference and comparison. Your version is clear. I just made it more native speaker style.

"I do not know the reason why I often worry about my future. I  especially seem to worry about my study and what job I  will do.I do not know the situation in  other countries,but the people around me often tell me that I must study hard and improve my ability or else  I will be left behind  by society. Also, really I want to offer a better life to my parent in the future.But so far,a year of my college life has already passed.I haven't accomplished anything except my score.I did  not work a part-time job,travel,or fall in love.I hope I can change myself."

*** I had similar feelings when I was younger but I can tell from experience that you will find your path. Many things will come to you that you could never predict now. Just keep an open mind and you will get what you need in life. Worrying about the future has little effect on creating you future.  (Just my opinion)
