Sing Me to Sleep

Fill for Blangst Prompt of the Day 794. Blaine becomes overwhelmed with NYADA and life, exhausted from lack of sleep that anytime he actually does lay down he falls asleep almost immediately. Then he gets hit with a bout of insomnia and can't cope. Kurt does the best he can, but they're both busy, and neither one of them notice it's a problem until it's almost too late.
