A naive, anxiety-ridden film student uses documentary to interview strangers about their first time experiences in order to overcome her fear of all things unfamiliar.

The logline describes an an interesting situation -- but not a plot. Unfortunately, "overcome her fear of all things unfamiliar", is too general to qualify as a specific goal.

The logline should state a specific objective goal she needs to achieve, something important, something she desperately MUST have or do. Or else: the stakes: what she stands to gain a lot if she succeeds, stands to lose if she fails.

You might want to include a ticking clock for this objective goal. (Like applying for grad school in another state, another country by a specific deadline.) This will force her to do what she needs to do before time runs out.

fwiw.
