Depression is such an interesting phenomenon, isn't it?
It has so many variables from person to person. There's not just one type, is there? No. There's literally hundreds that manifests in so many different ways within it's hosts. Some stays are for days, some are for weeks, months, or even decades. Some drag it's host to the ground and keep them there for long periods at a time, others are able to walk around, but with a feeling of a heavy burden weighing them down with each laborious step.
I do write a lot about depression. I suffer from my own type. I speak from my own experience from my own struggle with illness, because this is how I cope. Maybe your experience won't match mine at all. That's okay. With the unique way my brain is wired neurologically I have come to expect it likely won't. I'll write about it anyway, and possibly someone might see bits of themselves within these words and at least know they're not the only one experiencing them.
