Am I having depression or am I not?

Am I having depression or not?  That is the question.  Spiritual healers tell Derrick that I am not having depression, that it is all mind made.  Derrick tells me that I am not having depression.  And when I get emotional and blue, he thinks it is all my thinking.  He wants to go get off taking my medication.

Yet how do I explain my feelings?  Everything I say does not matter to him.  In fact, now even my siblings tell me to be strong and fight my thoughts.

Then again, isn't depression all about negative thoughts, feeling blue, feeling anxious?  I am in the midst of applying for incapacity and TPD for my insurance yet I am told that I am not depressed.
