Please! Review it! Thanks.

Correct grammar! Best you proof read your material:
Here is your logline corrected:
To overcome her fear of the outside world as a result of her mother's death and rape, an orphaned girl, who suffers from hallucinations, accepts the help of a stranger and moves in with him.

That aside this logline lacks its most vital component - a goal. What does the girl want to achieve in practical terms?

Lastly, the structure and wording of the logline could be better, for example:
After witnessing her mother's rape/murder an agoraphobic girl must [do something interesting] in order to achieve [a compelling goal].
