JJ was always in a constant state of panic, anxiety, fear, and sadness. His friends constantly blamed him for everything, his dad abused him, no one ever believed him, and everyone always thought that he was a bad person because of his dad.
This led him to have constant anxiety and panic attacks as well as nightmares. He cried behind closed doors, locking himself in his room in the chateau for hours while he hyperventilated and sobbed.
You, however, were his only acception. You had been his best friend since you both could walk. You knew everything about him. You held him through dark times.
You always knew when something was wrong. It was like you could sense it. You stuck up for him when the pogues were yelling at him or being unreasonable. You would always lay with him when he had nightmares. You'd help him through his panic attack and anxiety. You'd wipe his tears and listen to him for hours. You clean him up after getting into fights with his dad, you'd smoke with him, you do anything and everything he asked. That's why he loved you so much.
It was late at night. You had gotten back from running some errands. When walking by JJ's door, you could hear him gasping for air through rough sobs.
