Who sucked up my energy?

I met some friends during the weekend, to a kid's birthday party. I thought I had fun and as usual, made some jokes here and there. And then, today, I got two emails from two different people, worried about me. One said she mist my jokes and fun and the other one said I have become very quiet.
I am doing a survey about my performance at work, and one of the comments I got was "Express more energy, but not as much as Jeff", where Jeff is this guy that is 24/7 pumped up. He is so energetic that he can't just type, he has some weird gadgets that transforms his talk to writing.
In my head, i was thinking I have become really chatty. I find myself talking all the time at work and with my friends. So I am trying to figure out what is going on here and as I read back what they said, I see that they are not saying I am not talking. They are saying I have less energy than before.
WHO SUCKED UP MY ENERGY?
In my new job, I am dealing a lot with coaching and being coached. While I have taken the coaching seriously, I had a bit of resistance being coached. The group that is coaching me is made up of an experienced coach and a bunch of apprentices. The apprentices are all kids that just finished MBA, but dressed in contractor suits all day they look older. They are maybe 10 years younger than me but have the attitude "Listen to me, this is how it must be done". I have a problem with that. Pisses me off!!
So I took a position where I almost ignored them, especially a couple of them. I chose to talk with only a couple that didn't come with that attitude and actually knew how to talk and what to say.
On the other side, with my team members, we used our lunch time to vent off all the "Us vs. Them" issues we faced day in- day out.
One of the books I started reading for my new job, explained me something: There are 3 levels of coaching: Follow the rule, Break the rule, Be the rule.
I read it as just one of the things explained in the book, but then after that, it hit me. These guys, see us as contingent that MUST Follow the rule! While, we were hired to BE the rule. So we are constantly heading each-other. They do not want us to even Break the rule, just Follow the rule.
I am tired of this and I find myself constantly breaking the rule and trying to be the rule. But then I watched an episode of "The pitch". The story was about 2 ad companies competing to win the marketing role on a company that was focused on women products. One ad company was made by women, 100%. The other one was made by men with one women. The women from that team did all the right questions to push these guys to the right path of thinking. At the end she came up with the right pitch and they won. The company with 99% men won over the company made 100% by women, over an ad for women products!!! And guess what! The asswholes did not even recognize her contribute. They did not say "We won this because of you"! They actually complained about her way of debating with them and pushing them with questions and discussions!
I think I am probably doing the same for my team. I am being that women that pushes them until they make the right decision but because of my "feisty-ness" I am not recognized. So, I am getting to a point where I am stepping once notch back and let the others in my team step it one notch up. I am losing my energy! I am losing my attitude to talk and doubt everything I hear. Good/Bad?
The good part is that I will probably make it to recover my reputation at work. The bad thing is that I am losing my reputation with my friends. I am drained!
