The family of disgraced “7th Heaven” actor Stephen Collins, who was exposed as a serial child molester when an audio tape of him admitting to the decades-old deeds was recently made public, fears he may take his own life over the scandal.

Collins, who played an easygoing pastor father on the long-running TV series, has hit rock bottom in wake of the stunning allegations, the Daily Mail online reports.

His family fears he may hurt himself, according to a family friend.

“His family by no means condone what he’s said to have done, but it doesn’t stop them worrying about him,” the pal told the website. “They fear he could take his own life. That’s how low he is right now. No one wants to leave him by himself.”

Collins’ estranged wife Faye Grant admitted to recording his shocking confession during a therapy session in which he admits to molesting three girls – including one related to his first wife.

Grant also accused Collins, 67, of having incestuous thoughts of their unborn childwhile she was pregnant, TMZ reports.

“The comment you made just before I gave birth to our daughter when you said you hoped we didn’t have a little boy, because ‘you just didn’t know if you could keep his little penis out of your mouth’ was indication enough that you were sick,” Grant, 57, wrote in an email.

The couple, who married in 1985 and have a 25-year-old daughter, have been embroiled in a nasty $14 million divorce since 2012.

Reports abounded Tuesday night that Collins shot himself inside his Tarzana, Calif., home but responding cops said it was a false alarm
