A broken lonely business women must confront her own demons when she falls in love with a schizophrenic film maker.

It is quite difficult to come up with good Logline for psychological drama. Most do not have an action plot per se. It is about the journey of transformation (ascent or descent) of the main character. In?28 days nothing really happen. Most of the action take place at an retreat for alcoholic. There is no love story, no action story. It is just the realisation by Sandra Bullock's character that she has a problem and is on path to self destruction.

In the few movies where the main protagonist does not change, most scenario introduces a narrator/point of view character who is changed by the experience.
Scent of of a women is a good example of such trick.

Your lead character 'learning to lover herself' makes for a good internal goal but for the logline you need a solid external goal.

What is the story about?

Not sure if it's the grammar, wording or structure of the logline that's throwing me but I can't understand what your story is about much less the plot.

The MC is a businesswoman who falls for a filmmaker - this means it's a love story, but what event motivates her to achieve what goal and how is she going to do it?
