The fellow posters have given some great advice....you may be dealing with something demonic about that women (maybe a spirit of jezebel or other demonic spirit) that is trying to attack you b/c the Holy Spirit living inside of you is a threat to that spirit's domain so to speak....while the Holy Spirit resides in our spirit, our soul/emotions are vulnerable to attack....you have done good by praying up but before you enter your work place plead the Blood of Jesus or worship God on the way to work.....your spirit will have teflon coating so no negative spirits/things stick to you....the blood of Jesus works wonders!
I'm more and more convinced that there was something demonic going on in that office yesterday, and I am going to be sure to armor up from now on. I wish I had a pendant to wear too, and maybe yesterday's experience is the perfect reason for me to get on Amazon and browse the Christian jewelery.
