If you plan on helping people, I urge you to read what depression is. It is an illness, just like thyroid deficiency or cancer, it is not a "feeling" as you so eloquently put it.
Just so you are aware.
I work for the Health Service. MENTAL health. It is part of my job.
I would like to wager a bet that I am more qualified than you and work with more people who suffer from depression - so stop keep telling me to read about it and that I don't understand. I live it.
How was your diagnosis confirmed? Through tests? Or simply through you explaining to your Dr you feel down enough times for him to accept that you are depressed?
I know how it all works.
The image you are portraying is the reason you cant do certain things and don't feel pleasure is because of an issue and chemical imbalance in your brain.. How was this confirmed?
I KNOW/WITNESS that a large percentage of people are able to recover from depression do so by working with an IC to identify areas of their life they are thankful for and focusing on activities and goals which gives them a purpose.
Focusing on the things they are thankful for in their lives is the key factor to initiate the recovery journey.
So like I said, apart from going to your Dr and explaining you feel down etc.. What medical feedback have you got that identifies a chemical imbalance in your system?
