What really makes us stronger is recognizing our limits and finding help or someone to lean on before you hit rock bottom. They may not be able to prevent you from hitting the bottom, but they can make getting up a little easier. We aren't meant to go through life alone. That's what family and friends are for.
The more we strengthen each other, the easier things will get. Keep that in mind next time you help a friend through a rough patch. You give what you get and in the world we live in, every effort counts.
