Where can i find the silver lining?

My husband leaves soon (3rd deployment). I'm fine during the day but I cry every night thinking about what he is going to miss and our 3 year old asking "where's daddy?". Tips to make the deployment seem faster/more bearable? Tips to get me outta this sad funk? I wanna be strong for our kiddo bc I know cryin doesn't help but right now it feels like it's all I can do right.
