The boxing star can be seen in the footage -- which was posted to his social media page on Monday -- listening to Hillsong UNITED's "Oceans (Where Feet May Fail)" ... before he suddenly starts to break down.

In the clip, Garcia tearfully explains that he's "been going through a lot lately," but his faith -- and the love from his supporters -- have helped him get through it.

Garcia noted he was torn up over the fact that despite trying to do good in his community -- some tried to muzzle him ... and even cancel his upcoming megafight with Devin Haney.

"I was trying to do something good, you know?" he said ... adding, "I love you guys. And I appreciate every one of you guys. And I love all you guys."

Garcia ended the vid by promising to address his fans again soon.

It's been a whirlwind couple of weeks for the 25-year-old ... especially when it comes to social media postings. Since announcing his April 20 tilt with Haney, he's shared bizarre messages and clips frequently on both his X and Instagram pages.

At one point following a series of unusual posts earlier this month, he actually vowed to no longer talk about anything but sports, boxing, and his fight with Haney.

Clearly, however, he's still making content ... although Haney's father and trainer, Bill, said on Tuesday he's sure Garcia is fine and the fight will go down as scheduled.

"No matter how many distractions, no matter the antics Ryan has displayed, I know the kid ain't crazy," Bill said.
