Good morning.
The beginning of a monologue is no different than any other piece of writing; it needs to begin with an introduction related to what you are going to talk about later on.
I suggest starting in the middle and leaving the introduction part for last. After all, how can you write an intro describing something that you haven't written yet?
Begin to work instead by brainstorming what you want to talk about. Where is the first instance in this text where Romeo begins to think about committing suicide for love. Pull lines from the text that describe this and you can analyze and interpret them a section at a time. You can describe what you think he is thinking/feeling which is driving him to take such drastic action, or you can take a more "light-hearted" approach, describing a "what-if" scenario, as in what would happen if Romeo knew the truth of the situation? Would his "bravery" change?
I hope this helps you get started.
