SSRIs — selective serotonin reuptake inhibitors — are among the most prescribed medications in the world, used for depression, anxiety, OCD, PMS, and more. They work by blocking the reabsorption of serotonin in your brain, initially increasing its availability. But over time, the brain compensates by producing less serotonin of its own, leading to a depletion effect that many people feel as a general flattening of experience.
One of the most common — and least discussed — side effects is a kind of numbness: difficulty feeling sexual pleasure, emotional distance from people you love, a sense of living behind glass. A growing number of clinicians now recognize a condition called Post-SSRI Sexual Dysfunction (PSSD), where these symptoms can persist even after stopping the medication.

"Most people are never informed about the possible side effects to libido, orgasm, genital sensation, emotional connection or the nervous system… I see a medical world that dissects our symptoms into separate diseases when every single symptom is usually connected to the same things."
"It's a depletion. Initially it's a flooding of serotonin, which gives us this feel good, but ultimately it becomes a depletion of the serotonin… There needs to be an awareness of what's going on."
