I personally struggle with depression pretty regularly – pretty much every few months.
It always starts out small. Little things will start to get to me a little more than they usually do. My patience gets thinner. My fuse gets shorter. The things I normally enjoy seem less interesting than usual.
I reach out to friends less. I watch TV more. I spend less time playing with my son because I just feel too tired. I troll social media constantly looking for something, anything, that will give me a little excitement or hope. Of course, those things just don’t work, and I wind up spiraling down, and at some point, I just feel like I don’t recognize myself.
