LittleBlackDog, I see nothing boring about being responsible. I wish more people were conscientious and responsible, to tell the truth.
Just because you are unhappy does not mean you are stupid or pathetic or worthless. It simply means you are in pain for some reason. And people respond to life's challenges quite differently. Some are more sensitive than others.
You mentioned having a difficult couple of years. Would you care to talk about a anything specific that happened?
In the meantime, many hugs and much encouragement.
