When smiles turn to pain and the pain turns back into smiles, then growth in life has occured. It sounds as if you have grown.
You passed out as you were going through a door. You were crossing a threshold. Crossing a threshold can be symbolic of leaving the old life behind and going into the new. When you passed out at the threshold, it was like you were dying to the old life and re-awakening to your new life. Change can be painful in the beginning. But soon, the wounds heal, the soul is refreshed, the mind is at peace and you move on. You are through the door now. You've crossed the threshold. You are on your way. As always, go with God.
