I'm at a loss of words, any suggestions?

Develop Scripts. One way to deal with "not knowing what to say" is to develop templates or scripts. Another thing you can do is create 5 to 7 questions you will ask another person when you meet, such as, "where did you grow up?" or "what do you do in your spare time"? If you focus on learning about the other person and get them to talk about themself, it takes the focus off you.
