How do I get comfortable with selling Life Insurance?

I got my license to sell Life Insurance and I work at an insurance agency where everyone else sells it. However I am the only one here at the office and my co-workers are all in another state so I have nobody to help me. I already have prospects from my auto and home clients. But once they start asking questions and are interested in the Life Insurance I feel like I don’t know what I am talking about! How the heck do I get started. I dread it.
