I am not a sport girl.

I came to realize this lately. When I was in primary school and secondary school, I was never good at sports. I took PE and didn't always get good grades. Sometimes I did better in maths or English than in PE. PE classes made me anxious and worried. We learned soccer, handball, basketball, volleyball, running, and badminton. For clubbing, I tried badminton and rugby, then stopped at some point. One of my friends was the president of dance club when she was in her third year in the university. She invited me to her club one day. I went there and never returned. I can't swim. I tried ultimate frisbee and didn't like it. I used to bike when I was leaving somewhere but not anymore because my mother thinks it's unsafe. I like to walk. From time to time. That's all I can do without feeling lost.

This is already pretty good. I can maybe just make a couple of points about making it flow better.
