I Battle Depression

‘Are you happy?’ It’s such a difficult question. I always say yes, because 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.
But then, one night at 3am when I’m alone and still awake, lying in bed, thinking about life. I find myself crying my heart out. Suddenly, I convince myself that nobody likes me and they never will. I feel horrible and I question everything I had..
..and I don’t know if I was ever happy at all.
