Second Honestly

I'm sad. But i can look at people in the eye and say i'm okay. But i'm happy. And i don't understand how i can be? my life overall is okay. i have good days, i have bad days. And i have days here just want to sit in bed and cry but i'm happy. I don't understand how i can be sad but happy. I guess i just need more time to figure out. If there's enough time in the world.
