Depression is very hard to describe.My own memories of my worst situation are pretty clear but to describe how low i went i dont think words would be enough!
I also had family members who didnt take my depression so serious until they didnt hear from me for a long time they realised something was wrong.
Daphneflower have you been to see anyone about this? Or do you have any ideas as to why you are feeling depressed?
It depends on your situation and self as to how long it will last.With some cases it could be two weeks and others years before it can be resolved.So much depends on the situation and seeing an expert would probably speed it along fast.
But we are here to talk and listen if you need too
