I hesitate to offer any detailed advice, but I know Debi and others here put great stock in the pray to St Michael, the Archangel, seeking his protection. Apparently you don't have to be Catholic, or even a Christian to benefit from this pray. I personally wear a St Michael's cross. Here's the pray, hopefully it will give you some piece of mind in the short term until Debi or those more qualified than me can offer better advice.
