a pitch only review from me...
The title is okay I think-
The logline reads like Silver Linings Playbook with teenagers and without any hint of a specific plotline.
Your words would express the same if you would cut twelve words and just write: Two teenagers with mental issues fall in love.
Of course the words struggle and that odd 'life is hard' part at the end tell us about theme, location, time, tone, specific obstacles/antagonistic force, motives, premise, goals - no, not really.
Not convinced here. No clue why you think/thought that such an empty pitch would work.
