Last nigh I could sleep because I warried about it

I hope tonight I can sleep little bit, but I don't feel want to sleep. I hate that happen to me because tomorrow morning I will full sleep in the class. Oh yeah today, I suppose had to go to writing center, but I didn't feel well. I got headache that why I did go. This week had many tests. I should relax little bit. Usually, I go to writing center once a week. I would like to spend my time go to writing center for helps. I think this year I get a lot improve my English skills. I really have gratitude for everyone who helps me.
Later, I went to wait my older sister drove me home. I didn't have to spend $2:50 dollar. I could save my little money. I never ask someone to gives money for me. I work hard to make some money for me go to school. My salary only for my tuition. If this time I can't pass, I might stop school. I don't want to give up, but I really have heart time to do what I have do. I hope someone can understand me how hard I live in the Untied States.
Sometimes, I think something bad thing happen, I want to cry. I cry many time already. Usually, I tell myself to be strong girl. A lot bad happen to do and I have a lot work to do. Only myself know how hard of my life to live in the world.
