People left 'crying their eyes out' after watching new season of Netflix show

Viewers are balling their eyes out after watching a new season of an emotional Netflix show.

Check the trailer out below - warning - you might need a tissue box on standby:

It follows the friendship between best friends from their teens all the way to their 40s.

"What could possibly have ended the tight-knit thirty year friendship of Tully and Kate, our 'Firefly Lane Girls Forever'?" the synopsis for the second season reads.

"We'll learn the answer this season - but first - Kate grapples with the painful aftermath of Johnny's ill-fated trip to Iraq, while Tully faces a lawsuit after walking away from her talk show, and must start her career over from the bottom.

"This leads her to search for answers about who she is and where she comes from - including a quest to find the father she never met, against the wishes of her secretive hippie mother, Cloud.

"In the '80s, we see Kate and Johnny first fall in love, creating more than a little drama in the newsroom where they work, as Tully's career rises and she spars (and flirts!) with cocky sportscaster Danny Diaz.

"She just might have met her match - that is, if they can stop arguing for five minutes.

"While in the '70s, teenage Kate and Tully struggle to keep their friendship together as Cloud goes to jail for dealing drugs and Tully goes to live with her grandmother, far away from Firefly Lane.

"As the girls face the tumult of high school apart, they know the one thing they really need is each other."

After watching all nine episodes, fans were utterly stunned by the ending, which we are kind enough not to spoil for you.

"I have sobbed during every episode of Firefly Lane and now they just used ‘This Woman’s Work’ in a scene and I’m ugly crying the ugliest ugly cry to ever ugly cry," one viewer tweeted.

Another added: "Someone discuss Firefly Lane with me, crying my eyes out at 8am."

Someone else wrote: "OK I know I just said I don’t rave over shows but Firefly Lane also had me crying in damn near every episode I don’t even care if it’s corny that show hit cloooose to home."

If you love a good Netflix and cry sesh, you know what to do.
