Hey Indie Soul,
Yip lose of interest is 1 of the symptoms. Finding the motivation just isn't there and energy to do anything including eat(well for me) is a huge step. I have just achieved a goal and that is getting up at 930am and walking to a local supermarket then coming to my folks house. This is a BIG GOAL for me as I have been isolating myself recently.
We are all different in respects to symptoms but we are all similar with the depression
Hope you find some piece of mind
