Over the last three weeks I have been feeling heavy, tired/worn and sensitive. Sometimes, I cry for no reason and get very agitated that I just want to scream and yell. I also think about death a lot but I am not suicidal. Basically it feels like my soul is aching.

Shortly after I wake up the sadness and heaviness moves in. It seems to get better as the day goes on and tends to return before bed.

Life seems to be going well so I don't understand why I feel like this. Can one get depressed without having a reason?
