I have been playing tennis

My family has the same hobby which is playing tennis. I was play the tennis when I was 5 years old. I went to the tennis club twice a week for 9 years, because my elementary and junior high school didn't have tennis team. When I was a high school student, I belonged  the school team for first time, and I belonged  to the new tennis club too. I practiced six times in a week.
But I hated tennis since I was a high school students, because I wanted free time, playing with my friends and I couldn't get good prize. I have less stamina than any other club member, so practices were very hard for me and my coach is a very strict man. So I was very afraid of him. However, I couldn't tell him that I wanted to retire the tennis for my parents, because they were very eager. I hated tennis, but I went to practice everyday without missing.

When I had last year's general athletic competition, I was very nervous two weeks ago before. I couldn't eat anything. I lost weight about three kilogram. My mother was nervous, too.
I couldn't be a champion, but I could get third, and did the my best performance since my tennis career.
This year is my sister 's last year, so I want to support her with my exploited.
Now, I quit  the club team, but I want to play sometimes, and I want to tell my parents that thanks for teaching tennis to me.
