Why can't i never think of what to say to anybody? i'm socially awkward.

Ask questions: When you feel tongue-tied in social situations, remember the following: encourage the people with whom you're speaking to talk about themselves. Do this by asking them open-ended questions that you really want to hear the answers to! most people will feel flattered by your attention to them and to what matters to them. Be sure to do them the courtesy of remembering what they share with you.
