Joakim Noah has a ton of regrets from last season, and one of them is his awful campaign may have played a role in costing Phil Jackson his job.

In his first comments since the season ended, Noah also admitted he “lost my confidence’’ and “wasn’t moving right.” He said his drug suspension “hurt a lot of people,’’ and he has “to live with it the rest of my career.’’

But Noah added he is ready to redeem himself by being a model veteran for the Knicks’ young big men.

In breaking his silence, the Knicks center gave an emotionally charged, 75-minute interview with the “Truth Barrel’’ podcast. He beat himself up over the nightmare his first season in New York became after Jackson lavished him with a whopping four-year, $72 million contract. Jackson was fired in late June.

“It’s tough, man, because I got a lot of love and respect for Phil,’’ Noah said. “He gave me an opportunity to play back home. Somebody I read all his books as a kid. I was just a big fan and still am. I have a lot of respect for him. It didn’t work out. That sucks. It’s something I have to live with. He believed in me, and I kind of let him down. That’s frustrating. He got a lot of blame that it was his fault. But we didn’t lose all those games because of Phil Jackson.’’

Noah, 32, spoke philosophically about a year in which everything that could’ve gone wrong for him went wrong.

“I wouldn’t trade it for s–t,’’ Noah said. “I know a lot of people are mad about it, but I’m not. I don’t feel sorry for myself. Everything that happened were my decisions. I’m a grown-ass man. I’m playing in New York City. It sucked because I didn’t play well. I get to bounce back and come back next year. … I’m not going to quit.

“I know New York — I know if I can come back and get it right, that could be a big story, too,’’ Noah added.

Noah, the two-time All-Star, saw his play dip significantly. He was wracked with various injuries before his drug suspension finished his season. He had surgery on a torn rotator cuff in late April, after he was suspended for 20 games for testing positive for Androgen, for which he still has 10 games left to serve. He can’t play until Nov. 8, against Orlando.
