FATAL FLAW

Well, everyone has a fatal flaw, right? Someone gave me a reality check I needed. You know what my fatal flaw is? I overdo everything, and it may seem great when it is only the positive things, extra conversations, extra words of encouragements, extra kindness, extra sheets of paper, extra trying to win over people, you get the idea, right? This is the same thing I said to my interviewer for the CR position in the 3rd sem, that when i became the CR in the first sem, I was the only one who had applied, so I felt that i didn't deserve to be the CR, so what did I do? I overdid everything to "win" over people, it started with sending notes, but it then slowly matured into sending reminders and deadlines. I have always tried to do the same in my life, but the problem is I do that when I'm at my lowest too, so when I'm sad, I'll just act like a child, shut off all the doors, push people away and just cry alone, if I'm angry, I'll vent it out on someone (& get badly beaten/bullied back in the process). 
I'll try to change that though, since someone rightfully pointed it out today that I was losing my own self in doing this, and that is something I cannot afford to do.
