i don't know what to do

Today i played basketball with other teams. One of my teamates was absent and she was like the star player on my team. Now it was only me and these other 2 friends of mine. We were up against this team of 4 and we lost. When i started to play i had full confidence in myself. My best friend hates it when i always say bad things about myself. So basiclly is i tell her this she will get pissed. We lost 0-12 and i felt horrible. I felt as if i barley did anything. My teammates and i all agreed that we couldn't do this without the starplayer. I felt so hopeless.........that i didn't even want to try anymore. Each time i tried to make a shot i missed. It was my fault because i was depending on my teammates to make the shot. There was this tall dude who kept getting the ball away from us and making the shots. I always used to think that i improved in basketball, but now i feel awful. Basketball was one of my favorite sports and i suck at it. No matter how much i practice in basketball i fail. I alwways thinking of giving up on basketball...................i'm not sure what to do.
