Retaining courage during mediation

Everyone in this little community is awesome, and the people contributing have helped me in the path tremendously. Thank you. My question is this, how can a person remain calm and courageous during sessions? When meditating, I've been reaching very intense states that become hard to handle. I've been getting the sensation that I am melting into this state of pure love. I get scared because it's just so unbelievably intense, and feel that the fear that arises is a hindrance. Have any of you experienced this? If so, what did you change that allowed you to handle it?
