I often feel sad, especialy when I wake up, like this morning. If I think of the past, I feel sad. I don't know why.
When I think of the past, if it was something good that happened, then I miss it, and I wish I could travel back through time and experience that feeling again. But I know I cannot, so I feel sad.
But if I think of something unhappy that happened to me in the past, then I feel unhappy all over again.
So I try to shake it off. Of course, everything has gotten works since I quit smoking cigarettes two months ago.
