Caroline it sounds like you have to trust your deepest intuition.  It took a long time for me to become comfortable with this, but has been life changing.  Just quiet down (having a sitting practice is huge) and let the truth be revealed.  Yes there are many sides to every decision, so not saying just blindly follow your heart.  but rather use your inherent wisdom to gather as much information as you can and set your intention.  This has worked wonders for me, and I hope you are successful at your new job!
