A young woman struggles to cope with life in America after being orphaned by parents immigrated from war torn Lebanon.

This is a little confusing.

Can I suggest...

When a young Lebanese immigrant is orphaned, she struggles with her new life in America.

- or -

When a young orphan flees war-torn Lebanon, she struggles with her new life in America.

I also recommend including with the specifics of her struggle. For example, is she struggling the feelings of isolation? Is she struggling to find a long lost relative?
