Good luck to you. Heres a quote I fell upon that may help
Quote: Like the emotional symptoms, the painful physical symptoms of depression arise in specific nerve pathways presided over by the neurotransmitters serotonin and norepinephrine. From their base in the brainstem, such pathways travel up into the highest reaches of the brain, the frontal cortex, where they help regulate thinking and mood. They also travel up to the brain's hypothalamus, where they regulate eating, sleeping, and sex drive
