"are you happy?" is such a difficult question. 
I always say yes because I have an amazing family. I have friends, I laugh at jokes. 
I go out a lot and have fun, my life isn't' as bad as it could be, and I don't' have terrible problems. 
It could be worse, a lot worse. But it's not at all. 


But then some nights around 2 AM when im alone, still awake, lying in bed, thinking about life, I find myself crying my heart out.

suddenly I convinced myself that nobody likes me, 
nobody will ever like me. 
I feel horrible and I question everything I had 
and I don't know if I was ever happy at all.

We assume happiness is what happens outside of you but it's not.
Whether you are happy or not is a question of how you think and feel, and has nothing to do with the reactions of others unless you decide to live with that false belief. 

Sometimes I feel sad. Sometimes I feel happy, and sometimes I feel both at the same time.
