1. you tend to enjoy solitude
This isn't always a terrible thing. You find it peaceful-being alone with your thoughts- at least when they're not trying to attack you. it feels nice to have uninterrupted thoughts. It's so much easier and peaceful to think when nobody else is around you.
2.you think A LOT
sometimes, your overthinking leads to anxiety. Which is the bad side of thinking so much. But, your thoughts are always so much deeper and more complex than the thoughts of a normal person's. You can look at the stars and wonder about how the universe came to be. Instead of thinking "oh look. a star"
3. You have a deeper appreciation for good things.
a good day for any normal person is just a good day. But, for you, a good day is like a beautiful breath of fresh air after being suffocated. A good day for them is an amazing day for you.
4. you love the night.
This goes back to enjoying solitude and uninterrupted thoughts. The daytime is so busy and noisy. The night is quiet and lovely. Maybe you love the night so much because there's a darkness inside of you. But, you know what? How would we ever see the constellations if the sun never set? How could we see the rue, utter beauty of fireworks without the night? Darkness isn't bad. Darkness isn't scary. Not all the time. There is beauty in darkness, you just have to look.
5. You're an artist.
You write? poems? songs? books? are you good at it? your art is a reflection of your mental health. No good painter was happy all the time. No poet ever found love the first time around. No musician ever had it easy. The best artists are the saddest people. good art comes from bad experiences. No artist is ever a "normal person"
