Watch Me Fall Apart

Sirius is about to be 16, he should be happy, but he's stuck at home all summer without his friends and he feels like he's slowly falling apart. What's worse is that when James finds a way to get him out he almost doesn't want to go. What if James finds out his secret? Would he still be his best friend? No slash. Might be slightly OOC. M for self harm...could be triggering.
