Thanks for posting this Potty.
It's a subject that not a lot of people know much about, and that people are scared to approach because of "fear of the unknown". I'm glad you have posted this, and please don't apologise for talking about you are talking about a sad/bad subject.
You have very good information here.
Talking from experience, the best treatment for depression that I could recommend is.... talking.... sounds very simple but it really does help. You are correct in saying, it's scarily common. and that it's more than simply being in a bad mood.
These horrible feelings of feeling moody, upset, "down", can't be bothered to do anything or talk to anyone, not enjoying things you normally would - can last for days, weeks, months, and sometimes longer.
The most important thing for a person who feels like this, is to contact your doctor. They are there to offer support, and guidance.
Thanks for this potty
