There are always handholds.

"The thing I think we have to remember is that there is no finish line with depression, anxiety, or any other sort of mental illness. We’re on this path, and the path is constantly changing. Sometimes it’s flat and well-marked, and we can see all the way to the horizon....Other times, it’s so heavily shrouded in fog and mist, we can’t even see past our fingertips and we need someone to show us where the path is. And sometimes, we come to a wall that we don’t think we’ll ever get over. I’ve been staring at the base of that wall for weeks, and just now you helped me remember that there are always handholds to get up and over it."
