Mixed Signals, backstabbing take a pick

Well , today I was beginning to get more confidence back at work. During the course of the day. , I had to send an email ( internally) about a maintensce need on one of our properties. Well, I cc'd my team oh well. I get a response from the recipient saying " Tebet will take care of it" but then my boss on vacation gets a email from same person asking why my team was cc 'd. Well , it gets worse then one of my " fellow team members" calls my acting team leader and telling her that my boss didn't want me to send any emails even internally without getting her ok. So now, my new temp boss is nervous that I got her in trouble, then I have a coworker who is talking behind my back but smiling in front of me. And a new temp boss (already nervous) thinking she wasn't told anything by my boss before he went on vacation. I feel absolutely incompetent and the very lowest of low at this moment....
