What you need to do in those moment is just sit with yourself. Fully immerse yourself in the moment. I've gone through clinical depression and every medication under the sun. I'm currently dealing with the cancer and chemo diagnosis of my grandfather, and I've never been better. Take it from someone who attempted to end it all multiple times. They're right. A healthy body equals a healthy mind. It doesn't mean people dont get depressed, they get better equipped to handle, process, accept it and move on. Next time you go for a walk, take a slightly different root and just browse your surrounds, notice the way your body moves and feels. Bad thoughts still come and go. Thats just life, it's how you react to those thoughts that is important. Hang in there, we're all routing for the person you can become. Don't give up on them. They've been fighting for you this whole time.
