Hi, and welcome to CC GodsGirl3.
Keep asking God to give you the wisdom, and bravery to know what, and when to testify. Remember, God didn't create us all to be Pauls. We all have different gifts, and not all of us are intended to be "ministers".
There's an old saying that I saw many years back on a plaque in my Psychologist's office. It said that we should always be spreading the Gospel, and once in a while we might have to actually say something. It's the old "Actions speak louder than words" cliche. I'm sure that people are noticing you, and wondering "What's she got that I ain't got?" You're spreading his word more than you probably think you are. Opportunities will come. Take advantage of them when they do.
