What are Juliet's fears about drinking the potion Friar Laurence gives to her?

that it wont work and she will have to marry Paris and that she will be alone in a tomb when she wakes up. She also fears that the Friar Lawrence has poisoned the potion, she wakes up before Romeo comes to rescue her, she lives and ends up in a room with dead people, smelling the foul air, and that the dead Capulets' ghosts would come and haunt Juliet.
