Don't take any opinion as something personal that they have against you, on the contrary, they are facts presented that prove that you, at this moment, are not prepared to be a member of the team. I personally, would like to emphasize that when you just said "just (want) to help" it is not a great and only reason to be convincing . Scarl said above, before becoming a helper you need to demonstrate with your behavior that you are prepared to be, and not wait to reach helper status, to be useful to the players. I believe that if you work on these aspects, you will be accepted in the future.
