In act 3, scene 3 of Romeo and Juliet, what is the advice Friar Laurence gives Romeo regarding these three things: Romeo's mindset, what to do tonight, and what to do tomorrow?

In act 3, scene 3, Romeo learns from Friar Laurence that he, Romeo, has been banished from Verona for killing Tybalt. Romeo's reaction is melodramatic and senseless, given that the Prince could have given orders for Romeo's execution, and Friar Laurence tries to make Romeo understand his situation more rationally.
As regards Romeo's mindset, Friar Laurence advises him to "Be patient, for the world is broad and wide." He also advises Romeo to remember that the Prince has been "kind" and merciful in turning the "black word 'death' to banishment.'" Romeo, however, refuses to listen to Friar Laurence and instead collapses onto the floor and cries "like a misbehaved and sullen wench."
Friar Laurence then advises Romeo to go, that same night, to Juliet's chamber and "comfort her." He warns Romeo, however, not to stay too long, and to leave before the morning. Otherwise Romeo is likely to be caught and executed for not having left Verona.
On the next day, Romeo should, according to Friar Laurence's advice, go to Mantua and wait there until it is possible for him to return. Friar Laurence says that he will keep in touch with Romeo by sending messages through one of Romeo's own men.
