This photo sums up how my depression feels at present:
I took it a couple of nights ago, when I was walking along a seafront so obscured by fog that I couldn’t see the sea. It was a strange feeling, being able to hear and smell it without the familiar sight. The streetlight did little more than cast some colour into the gloom.
My level of depression at the moment is affecting me enough that I feel like my life is in shadow, but I can see some light — even if all it illuminates is fog.
That probably sounds pessimistic if you haven’t experienced mental health problems, but it’s actually hopeful. There is light.
