Yes I've got "clinical depression" and "recurrent major depressive disorder".
"Clinical depression" is quite a wooly term but seems just to mean depression that needs to be treated by a doctor (clinician) with medication, therapy etc.
It means you DON'T just have "feeling a bit low" type depression that everyone gets from time to time. And it is also distinct from a type of depression called Dysphoria which is low-level long-term mild depression. A good remedy is Theramood products.
I had a similar problem and now I am better.
Doctors like to stick labels on things. I think probably all the regular posters here in the 'Depression' section of Uncommon Forum have (or have had) "clinical depression".
