It's ok to sit in depression and feel it. Try to ask yourself what you need right now. Maybe whip out some coping skills. Take a nice bath with some bath salts and candles, do something for you. Cook a dessert or something else you like. Try a new recipe. Here's a list of stuff to try. https://imgur.com/a/Hymn1. I'd also suggest left handed journaling. Get some paper and a pen and write down a question about what's going on with your dominant hand and write a response with your nondominant hand. It's pretty interesting what comes out. Just remember with bipolar things will eventually even out, sometimes you just have to white knuckle it until it's over. Depression isn't a negative feeling, most people get depressed at some point in their life. Just gotta remember our brains don't work right and the chemicals in them go haywire or we get too stressed and our brains go kaput. It's ok to cry and let out the emotion. Things will get better. Just remember it hasn't always been like this and things will change again.
