Well, I don't know why I picked BF to say this but hear goes.
I am asked at times why I don't have or want children. I usually (always) lie. Environmental concerns, etc.
Actually I suffer from depression and would not wish this on my worst enemy. It is the most mentally horrible symptom any one could ever have.
It is hereditary and my Parents have told me about it. My family suffers from it in some way or another.
No one knows the helpless-ness, the feelings, suicidal thoughts, etc. associated with it. Some days are better than others.
I want no sympathy, I just wanted to express a state where the closet opens.
