A famous singer with everything to lose and the car accident and subsequent trauma threaten her career, then she found her love and wants to make a comeback by doing a hit song again.

As Lotcher has pointed out, she has no goal, and as she's only aspiring, she has nothing to lose. Maybe make her a famous singer with everything to lose and the car accident and subsequent trauma threaten her career. Her goal then is to be back on top with a number one song again. Just an idea.

Overall this Logline can be simplified to 14 words (as opposed to 23 words) with, "A near-fatal car accident has an aspiring singer downwardly spiral into drugs and depression." ?This makes room for the Goal, Stakes and Antagonist, all of which are missing making this a sentence rather than a Logline.

So when editing this ask yourself: What is her goal, what are the stakes and who is the antagonist?
