The former Friends star gave up her Beverly Hills base last year (11) in search of a place to call home in the Big Apple, where she grew up.
But Aniston has since returned to the West Coast with her boyfriend Justin Theroux, admitting life in the city wasn't what she remembered from her youth.
She tells Australian radio's The Kyle and Jackie O Show, "We tried New York (but) it felt like I was (living) in a fishbowl.
"Justin still has an apartment there… It was a little rough with the paparazzi. It didn't feel like the New York I grew up in and knew."
Nevertheless, the actress insists her current level of happiness is off the charts at "10-plus".
She adds, "You have a more relaxed sense of the world and life, and you realise there's nothing to be taken too seriously besides doing your work and being a really good person."
