In native culture many believe a camera steals a bit of your soul away and traps it in that moment in the photograph. Some people also believe a soul isn't something you're born with but you earn over time through prayer and sacrifice.
I don't feel you can loose your soul, or pieces of it. For argument sake if you lost your soul, I feel you would slip into a coma as your body would still work but what makes you you [from a religious view not a scientific view] has left your body, and until it has returned those things [like emotions and memories] are lost. I don't feel as though you could loose your soul, maybe shards or pieces, but with person strength and your spirituality it can be repaired.
Speak with a spiritual leader, or someone spiritual you can talk to. If there is no one, meditate on the question, or ask your personal deity. The divine is within us, so you can speak with them.
