I'm sorry, but your cousin's mom's goofy nickname for them is not a relevant anecdote.

I have been on several and I'm speaking from experience. They do not make you happy. They do not induce euphoria. What they do is relieve depression. Instead of being nonfunctional and crippled, you get some energy and mood back. Ideally, enough to let you work on other things and help you get back to stable.

Plenty of people only need them for a limited time, and that's just fine.
