To anyone who may be in this kind of situation, trust your instincts and leave. It will not get better. You will find other, better opportunities elsewhere. Best lesson I ever learned was from a high level exec that had just started at the company where I worked. He quit in 2 weeks. Impressively, he did it without drama or really even causing bad will - he just told the CEO it wasn't a match, and that the longer he stayed the more detrimental it would be to both himself and the company. I wish I had followed his lead - I was too worried about what it would look like to leave a company so soon after joining.
