Nikki was going through a period of depression. It was because of his heroin and coke use. And he felt down and just non motivational all the time. He wouldn't shower often, he barely ate. He would try to be happy at band rehearsals, but he was just reminded of how he should've stayed home and not have gone out of the comfort of his bedroom. You were his partner. He was kinda distant lately, he wouldn't call you as much or invite you over. One day you were worried about him. So you came over to his mansion check on him. You arrived at his house and his front door was unlocked. You walk to his room and find him laying in his bed. Wrapped up in his blankets, muttering negative things about himself. How he hates himself and wishes he could disappear from the world, and how no one would miss him. He sounded like he was sniffling. You walk over to him and gently place a hand on his shoulder.
