Yes I feel this way at times. I think it is called depression. The doctor recently asked me if I had ever been depressed. I said, "Do thoughts of running the car of the road count as depression?" He then countered with, "Have you ever taken anything for depression?" I said, "Well, I had a doctor prescribe some pills but I was too depressed to take them!"
I have found that in these times if I do count my blessings it does change my mood. These dreary thoughts are just thoughts after all. You have the power to dwell on them or just release them and replace them with positive more life-affirming thoughts. Thoughts lead to actions so the next thing you know you are back enjoying life again with nothing but blue skies instead of gray emptiness.
You are a writer...shake it off and start writing. ;)
You have something very important to share with the world. We are waiting to hear what you have to say. Use your imagination to color your world with hope. Wow, that sounded sappy but nevertheless I do believe it is true.
