Elana has a vitamin B12 deficiency and she is very very tired. She has been feeling exhausted for months. She is always tired. She wakes up tired and spend her day feeling napping no matter how many monsters and cups of coffee she drinks she is always tired. Her work is suffering due to her exhaustion and no matter how tired she is she still can't rest. She lays down and she can't shut her mind off so she lays there and she yawns and yawns and tries to rest but never has success.
