I guess it's part of the process, once we reach our limit, we break down and get back to the drawing board, learning what we did wrong and start the process, again.
The hardest part is usually when shit hits the fan when we least expect it. For me, it's like sinking into a black hole and entering a different dimension, the proverbial black pit that's blacker than black. The trick is I don't fight hard to get out of it, I just let go off everything, total reset, so to speak.
Glad to know that you're at least back on track already, keeping moving forward even when you're going downwards :)
