Carmen has most likely been diagnosed with depression.
Explanation:
Selective serotonin reuptake inhibitors are most commonly prescribed to treat depression. These drugs treat depression by increasing levels of serotonin in the brain, which is one of the neurotransmitters that carry signals between neurons. They block the reabsorption of serotonin into neurons, which makes more serotonin available to improve the transmission of messages between neurons and thus ease the symptoms of the disorder.
