That's not too bad. One thing is that you need to focus more on your tense. In this case it's past continuous tense.
In everyone's life they have a special day for themselves. I had one of those days. That special day was the day I left home to go to a high school boarding house. The day had lots of fun and sadness. I cried every night because I was at a boarding school. I cried because I was homesick, and everything around me was new. I cried so many times that I lost count. In time I realized that I had to grow up and become more self reliant.I began meeting new friends, and I did not feel alone. My friends shared food from their hometowns. We studied and did homework together. At that time it felt like it was my second home. Happy times were also sad. People living together will sometimes struggle, but it is important to talk strait with each other and remain calm. During my three years in boarding school I learned a lot of useful things, and had affectionate sentiments towards my friends. When we graduated we remembered this special story about independent life and fun experiences with friends.
