Buffalo Bills star Mario Williams denied Monday he ever has had suicidal thoughts and said any pain-killers he took last season were prescribed and dispensed by the team’s medical staff.

Williams also gave no indication that he’s ready to give up on his court battle to win back possession of a ring worth $785,000 from Erin Marzouki, his former fiance.

The Bills’ defensive end spoke for almost 10 minutes after practice about the latest back-and-forth developments in the suit, which he filed earlier this month in Harris County Court in Houston.

The lawyer for Marzouki on Friday released a series of text messages allegedly from Williams to Marzouki and sent Nov. 11, the day the Bills played the New England Patriots in Foxborough, Mass. Among them:

• “I took 3 hydrocodones this morning and no one knows. I’m going to take 2 more on the plane and fade away.”

• “No money in the world should leave me with suicidal thoughts.” And: “I need to go back n my shell. There’s no telling what Ill do to myself at this point. I’m sry Ill disappear from now on.”

Williams did not deny he sent the texts, made public by Houston-based lawyer, Tony Buzbee. Williams called the texts “blown out of proportion” and “completely out of context.”

Regarding suicidal thoughts, Williams said: “In my situation, I’m completely fine. I’ve never had any inclination of anything that even myself would notice.”

Never in moment of anger did you suggest you might kill yourself, he was asked? “In a moment of anger, I talk about everything, I tell you that,” he said. “And I don’t know who would say they don’t. So that answers your question.”

Asked again later on if he had suicidal thoughts, Williams said: “No, no, no. Like I said, in the heat of battle, in the heat of ups and downs, things like that, you just come to somebody who you think you can just vent to, and whatever comes out comes out.

“I think that’s just a way of venting out, but obviously that’s the wrong person to vent to,” Williams said of Marzouki. “It’s just something that I wouldn’t tell anybody else – as far as venting – than the person you love or whatnot at the time.”

Regarding the use of hydrocodone, the 6-foot-2, 292-pound Williams said: “Anything I take is 100 percent prescribed and given from here. And in case you didn’t know, I’m a big person.”

Hydrocodone is a pain-reliever classified as a narcotic. Williams said he was given the medication for a painful wrist injury that he dealt with all last season. He had surgery on the wrist last October but did not miss any games.

“The whole situation happened with my wrist last year; obviously I was under a lot of pain,” he said. “I couldn’t even do a push-up or anything like that. So imagine going against somebody my size every play and battling with your hands. Yeah, I mean, the pain pills were directed from here.

“Everything you get, I get it through here and you take it as you’re supposed to take it,” he said of medication from the Bills’ doctors. “I think if you were to ask any football player or anybody who goes through injuries and stuff like that, sometimes one, two, three, it all depends on the person.”

Regarding the amount of pain medication a man his size requires, Williams referred to surgery he had in 2011 while playing for the Houston Texans to repair a torn pectoral muscle.

“I remember when I had my pec surgery, I think they had to bring in a whole ‘nother morphine machine for me,” he said. “Because stuff like that doesn’t hit me, it doesn’t affect me as far as helping out. It varies on what it is and how it is.”

In his lawsuit, Williams accused Marzouki of breaking off the engagement in January. He alleged that she never had any intention of marrying him and accused her of using their relationship as a way to get money.

Williams’ contract with the Bills – worth $100 million over six years – is the highest for a defensive player in NFL history.

As a former No. 1 overall pick in the draft, Williams was among the higher paid players in the league for six years in Houston, too. To date, he has made about $87 million in salary, before taxes.

Marzouki filed a countersuit alleging that Williams repeatedly broke up with her only to reconcile during their 10-month engagement and told her to keep the 10.04-carat ring after their final split.

A court-encouraged session to mediate the dispute between Williams and Marzouki was held Friday in Houston but proved unsuccessful. Buzbee said he filed a request to examine Williams’ cell phone, a standard part of discovery in such a case. Williams has 30 days to surrender the phone.

Buzbee told The News he released the text messages to provide a glimpse into Williams’ behavioral state when it came to his relationship with Marzouki.

“He vacillates between periods of deep lows and being very high on life,” Buzbee said. “During those low periods, he doesn’t want to be in the relationship. I feel like this is a soap opera, but this is the life he lives.

“People say, ‘She should give the ring back.’ You don’t stay with somebody for over five years and put them through all that turmoil he put her through and then file a public pleading, calling her a thief and think she’s just going to roll over.

“Our effort is not to embarrass him,” he added. “It’s to defend ourselves.”

Williams sees it differently.

“I never wanted it in the first place,” he said. “This is all the request of the other party that wanted to initiate all this. I’ve made it known this is just going to get bad, and neither one of us, you know, wants that. But you get what you ask for. But in my situation, my skin is unbreakable. It could be something next week, I really don’t care,”

Pointing to the Bills’ symbol on the team’s fieldhouse turf, Williams said: “This is all that matters to me – and that logo.”
