Zayn's younger brother Niall always had a hard time in school.
He got shoved around and called names and beat up. He self harmed and overall hated himself.
Zayn never really understood any of it, he could only ever just worry. His brother was diagnosed with depression, intermittent explosive disorder, post traumatic stress disorder and parasomnia.
Niall had been on heavy medication for a while and through a lot of counselling that to Zayn didn't seem to help Niall much.
Zayn grew up watching his younger brother crumble and take pill after pill. Eventually Niall got sick of his pills.
He took them all in one go, and got admitted into hospital.
The consequence? He was never prescribed another pill again and began to face a nasty aftermath.
But that nasty aftermath lead to Zayn. So maybe it wasn't so nasty after all
