Should I act on this or let it go?

I’m am on an basketball team- but also a dance team. I attend basketball thrice a week and dance twice. Basketball is technically four times a week, but I have dance that day, so I skip it. Usually we have games on the days were supposed to have practice, and sometimes I will have something else to do that day, because games last until like 9 pm. So yeah I’m not completely DEVOTED to basketball, but I try. All the people on my team think I Half-butting it because I miss games and stuff. People are sarcastic saying like ‘its Nice to have you at practise’ And then rolling their eyes after. What do I need to do???
