Serotonin is the hormone what makes us happy, so why aren’t we just injecting it into our body/taking it as tablets to get out of misery on command?

It’s weird. The brain is made up billions of interconnected neurons. Networks of these neurons work together and with other networks to regulate behavior, emotion, movements, and all other brain functions conscious or unconscious. SSRIs are a class of medications that block a channel of communication between individual cells, causing the network around it to change. Whats funky is that we can’t predict how it changes—all we know is that when we pull on this metaphorical lever, some peoples mood and anxiety get better.
