Depression is...
getting in a fight with your significant other
and having your mind tell you they are going to leave you
not because you think they actually will,
but because the depression part of your brain wants you to feel alone.
So you isolate yourself. Shut down. Ignore everyone.
Nod and say you're fine when they ask if everything is okay.
But you're not okay. They don't need to know that though.
Because maybe that feeling will go away in a little bit.
And it does.
But it will be back.
