Drowning.

Alice has been suicidal since she was 11 when her father left and everyone made fun of her and told her that her father left her because she wasn't good enough. She's attempted suicide about 7 times in the last 5 years, been to 3 mental institutions but has been let out by acting like she was happy and that she didn't cry herself to sleep every single night. But, after moving schools, again for the 5th time this year, she finds a man who's just as depressed and sad as her. One night, one beach party changed everything. She finds him trying to drown himself and she saves him but, he also saved her.
