What Is Melancholic Depression?

I'm going through cbt treatments.

I have had this condition since I was a child, invoked I think, by my mother's death at the age of six. I have tried to get help and have been to see many doctors but nothing, so far, has worked. Most often I believe my condition is being underestimated and that they think I am not really unwell. But everything that you say is what I feel. I took an online test and score 23/25 for this condition and finally have a call with someone to discuss it again, thirty years after I first tried to get help.
