Are you taking proper care of your Black Dog? Taking it on regular walks? Feeding it a nutritionally balanced diet? Giving it enough attention? A neglected Black Dog will only grow, growl, and consume you entirely.
My photography teacher referred to depression as "the black dog" and that image has stuck with me ever since. I've recently been analyzing my mental health, and taking steps to care for myself and my illness. It is an invisible illness, but left unchecked, it can take a toll on your energy and productivity.
If you're living with mental illness, please remember to check in with yourself every now and then. I've tried ignoring it and acting like I'm free of it- and that has only led me to bad places. Acknowledge it, and take the time you need to learn strategies of coping that truly work for you. Find your balance.
