Dana Carvey is still deep in grief over his son Dex's death a couple months ago, but he's hoping getting back to work with his buddy David Spade will speed up his healing process.
The former 'SNL' star spoke for the first time about his family's painful experience since Dex's fatal overdose ... telling David during their "Fly On the Wall" podcast return, it would be cool to laugh with him again.
TMZ broke the story ... Dex passed awayin November after his GF called 911, and first responders found him unresponsive in the bathroom of an L.A. home. Paramedics tried unsuccessfully to bring him back to life.
Not long after, Dana revealed he died of an accidental drug overdose while paying emotional tribute to his "beautiful" son.
Dana was inundated with well-wishes and support following the tragedy ... and he thanked everyone for all their sweet comments and well-wishes.
