Has it been six seasons already?

It seems like only yesterday we met NeNe Leakes’ big personality and Kim Zolciak’s wigs.

Now the entire case of Bravo’s mega-hit “The Real Housewives of Atlanta” is back — and stranger than ever.

NeNe re-married her ex-husband, Gregg. Kim is off the show and pregnant with her fifth child. Kandi Burruss is getting married to a guy who worked in production on the show — and her mom isn’t happy about it. And Porsha Stewart, who’s battling her NFL husband Kordell, claims that he might be gay.

It was a pretty heavy episode last night. (I’m sure Bravo execs were happy.)

But it left me thinking, “Why did I just waste an hour of my life watching this?”

A friend of mine posted on his Facebook wall last night — I’m assuming after watching the premiere, too — “An hour and a half spent watching Bravo and I think I’m now 25% dumber.”

It was, well, depressingly true.

There was nothing I gained from watching it except that prenups are awesome and false lashes work miracles.

But Bravo’s onto something.

Apparently, we love reality TV. (Or most of us.) There aren’t many people who have never heard of reality celebs like Omarosa Manigault (“The Apprentice”), Bethenny Frankel (“The Real Housewives of New York”) or Elisabeth Hasselbeck (“Survivor”). These people have become mainstream brands and they have reality TV to thank for that.

Since 2006, Bravo’s “Real Housewives” franchise, to date, has run 40 seasons, totaling more than 580 episodes. It has spawned spinoffs — “Vanderpump Rules,” “Bethenny’s Getting Married,” “Don’t Be Tardy,” “I Dream of NeNe” — with millions of viewers watching with bated breath for the next drama-filled episode.

But why?

I, too, am enthralled with reality TV. When it’s on, I’m glued, my brain shuts off, I turn into a VanderZombie. But like eating a box full of cheap chocolate, I’m never satisfied when it’s done. In fact, I feel a little sick.

Anyone else feel the same way?

Please tell me it’s not just me.
