A source told ET earlier this week that Spelling had a meltdown at her home due to multiple stress factors that she's currently dealing with.
“There are several things that led up to this, and she really couldn't take the pressure any longer,” the source said of Spelling. “Tori tries to be the best mom she can be, but with five children and terrible financial issues, her marriage has suffered tremendously.”

According to the source, she and her husband have also been arguing over money and their five children. McDermott had left the house for a couple of days for a break, which is why when he came home on Wednesday night, Spelling thought there was a break-in.
An LAPD spokesperson confirmed to ET that there was a call for service of a burglary at Spelling's address on Wednesday night, but it was determined that there was no crime.
"She had no idea he had walked in the door and it scared her," the source said. “She is obsessed with trying to make her relationship with Dean work despite all their issues. Her breakdown came after she and Dean had been fighting. She literally was hysterical and, sadly, the kids were home and everyone was scared. ... She is under far too much pressure."
