Doc Gooden -- I'm Done with Strawberry Beef ... 'Moving On With My Life'

Doc Gooden says he's officially ending his public feud with Darryl Strawberry ... telling TMZ Sports, "I'm moving on with my life" after trading nasty barbs with his ex-Mets teammate.

Things went south between Doc and Darryl on Thursday -- when Doc no-showed at an event and Strawberry chalked it up to drugs.

"My fear is that -- and I know addiction -- and my fear is people that don’t change, they die," Strawberry told the crowd ... "I just hope the light comes on soon before it’s too late."

Gooden was PISSED -- and responded on Monday night by not only declaring he's been sober for 4 years ... but also accusing Strawberry of infidelity.

"Darryl has a drug rehab in his name, he is supposed to be a pastor. I call him Lucifer," Doc said.

But Gooden now tells TMZ Sports he's calling off his attack -- and officially ENDING his war on Strawberry.
