Spiritual battle at work is getting thick!

Hello everyone I could use some prayers. I am a firefighter and I work with many different people. Unfortunately most of the guys I work with now are non believers and very steeped in the world. This evening proved to be a rough evening. I was "attacked" spiritually and it's weighing heavy on me. I was "attacked" spiritually a few weeks ago as well. This is an ongoing battle that isn't getting any easier, I could use some saints to lift me up please. Tomorrow I need wisdom for a conversation that may or may not happen.... if it does happen I need strength, I will be a sheep taking on a wolf. If it does not happen I just need prayers for peace on the entire manner. Thank you so much
