Following their deaths, Health Secretary Matt Hancock said reality TV shows have a duty to care for contestants after they become famous.
He added: "I was in a dark place [after the show]".
The TV hunk, who entered the ITV villa a year ago, was only on the show for a few episodes but he found himself catapulted into the reality TV circus of parties and premieres.
"Everything has died a death, you've fallen off the cliff of reality fame".
Fortunately, Alex - who left the show after Megan Barton Hanson picked to be with Wes Nelson over him during a recoupling - was put back on the right track as one of the Love Island producers spotted one of his social media rants and pointed him in the direction of a psychiatrist.

He said: 'I had a little rant on Instagram.
He explained: "I didn't want to talk to anyone about it, but after having ranted after answering a fans questions and speaking to the Love Island psychiatrist, it got me through it and gave me a plan on how to take my life forward and now we're here".
Mike Thalassitis, who appeared in the 2017 series of the dating show, was found dead near his home in Essex on Saturday; which comes less than a year after 2016 contestant Sophie Gradon was found dead at her home. Looking back, all I needed to do was be forward and go talk to them'.
Following their deaths, Love Island producers said "bespoke training" will be offered to all future contestants.
The care will specifically help the stars get to grips with social media and financial management after leaving the villa, with many who appear on the show finding it hard to adjust to overnight fame and intense media scrutiny.
ITV, the network that airs Love Island, says the show's medical support is being independently reviewed.
And while on the show, contestants are monitored for any signs of problems developing, Love Island said.
