I... I honestly don't know why everyone is asking other people their opinion if they should resign or not. I mean, its YOUR resignation.
If you feel you need a break from the server, no ones going to stop you. No ones going to force you to reapply. My thought is, if its to much for you, decide that on your own and don't ask others for their opinion on the subject. You've done some pretty good work for someone of your age. I honestly didn't even know you were that young. If you feel you wish to leave the team. Good ahead, don't base it off of anybody else's choice.
