A letter from Romeo

After Romeo is dead they find a letter he wrote, that he apparently intended someone to find near his body. The Prince (chief of police and mayor of Verona all in one) read the letter. In lines 288-290 the Prince mentions it:
And here he writes that he did buy a poison
Of a poor pothecary, and therewithal
Came to this vault to die, and lie with Juliet.
That's all we know of the letter.
I would like you to pretend you are Romeo, in a hurry to go to Juliet's sepulchre and die, but wanting everyone to know what happened to you. Write a short letter to the people of Verona explaining whatever you think needs explaining.
