If there is one thing I can advise you based from my experience this is it: when you're sad and you need an immediate solution, choose between
1. Watching anything about the universe
2. Or listening to a good, good song
I have been playing Skinny Love by Bon Iver on repeat; morning, afternoon, and night. There was never a day last week that I didn't hear it. Also, I watched Discovery Channel's Curiosity Episode 1. I've started Carl Sagan's Cosmos too. And now, I was introduced to Ben Howard, a guy who's voice soothes my inner pains like a balm. People like him makes me grateful for so many things.
