Letter 311:
Lost In Emotion

Here Clarissa has become completely paranoid and frantic.  She does not know who she can trust and does not feel she has anyone she can rely on.  Lovelace always manages to corrupt those she comes in contact with.  She is lost in emotion.  She is filled with self-pity and lacks the ability to keep herself together.  
    She begs the Lord for mercy and claims she is the poor Clarissa Harlowe.  She is asking the Lord for help because He is possibly the only one who can help her now.  The reader also gets the feeling that she is attempting to make Miss Howe feel pity for her friend and the situation she is in.  She wants Anna to feel that Clarissa is completely stuck and the world is corrupted by Lovelace.
