Down is not always bad. A seed must go down in the ground, before it springs up into new life. Down can actually be a moment of re-birthing and re-energizing. The key is that it be looked at and treated that way. My logos for many years illustrates this truth.
It does not matter how far you have went down. As long as you humbly [not arrogantly] ask God for help; you will get it. Furthermore, it has been my experience that He will probably bring you back up higher than before (like a superball). Additionally, to make sure that you get the message, He has put people on your path, like me; to help you see this truth.
