Thoughts You Can't Express

Sometimes there are things in life that you can't do anything about. You just have to live with it. I always have this feeling, and I don't know what it really is. It's not happy, sad, or angry. It's just there. Deep in my mind this feeling that won't go away. What do you say when you don't know what you're even feeling? What do you do? Breathe. Just breathe.
