I liken my mood, or feeling to walking on a tightrope that is only a foot off the ground. Keeping my balance means I can see the light at the end of the tunnel. Touching the ground means my anxiety is high, and the resulting depression of thinking I will never walk the distance without falling. Happy and sad exist right next to each other for me,in that I am never so far way from one or the other to not still have a good view of it.
