What's the problem?!

I admit, I'm shy. It's kind of annoying to me. I meet new people and find myself struggling to start a conversation. And then once a conversation gets going I find myself struggling to keep it going. Moving to Indiana and starting at a school where I didn't know anyone, along with moving to Evansville and starting college this has become quite apparent to me. It's something I worry about and waste time thinking about. The bigger problem that I face is sharing my faith. Yep, I know I'm not alone when it comes to this, but I want to share my story I just don't know how to bring it up really.
I wear things that stand out, are different, and have an important meaning to me. I wear a bracelet that says, "I AM SECOND", meaning God comes first in everything I do, I put him above all else, and I put myself second.  A few people have asked me about it, but I find myself struggling to share my story and the love of God.
I wear a ring on my left ring finger that says, "True Love Waits". It reminds me how important my purity is, that it's a gift for my husband, and to never ever ever give it away till I get married. Once again a few people have asked if I'm engaged, or have children (weird) and I just politely respond saying 'no'. Yet again I could respond by saying no but this is what it means to me....
So what's the problem? That I'm shy and can't bring myself so share something so exciting and life-changing. Yup. I've been given this boldness and happiness that others need to hear and I'm holding it in. I hope that one day I'll overcome my fear of talking to others that I don't know and just share my story. May God give you the same boldness that I long for.
