You are now aware more than ever before how much you are loved and the singular honor and favor you now have before God.
In the beginning there may be long periods of silence, where you do not want to say things just for the sake of doing something. Fine. Wait. Your Lord the Holy Spirit will tell you what to say and when to say it.
When you are prompted, awaken your being to the invitation, and in Spirit and in Truth, respond as best you can, with all of your difficulties and uncertainties.
But... be honest and truthful in what you say.
