spirit of rejection

Well..in the midst of a week..i had this sudden feeling..its the feeling of rejection..dont know why..but it just popped out out of a sudden..maybe its because im having lots of friendly matches recently..then wasnt really helping much in the team..can sense that they arent really happy with my performance..
Maybe im just thinking too much..cause im being hurt before during my primary school once..hence..i tend to think alot when it comes to working in team..
How should i overcome this fear in me?i really feel very uncomfortable during the past few friendly matches we have..even though my coach feels that i have tried my best..but then i have the feeling that my teammates dont think so..
