Sometimes when you hit rock bottom there is no way you can move again on your own. That is actually the perfect time to just find the strength to do one simple thing: BE VULNERABLE. Call your friends, call your family, call a therapist, who ever seems to make more sense to you at that moment and time. Call and say: "I need your help". First of all you may be amazed by how many people are willing to help and on top of that you make them feel good. They are your friends or family or therapist and they just want to help. Wouldn't you do the exact same thing if someone were calling you?
Here is a beautiful video about vulnerability. So is vulnerability a weakness or a strength? I let you be the judge.
