The reality star - who shocked fans when he walked away from the ITV dating show in 2018 - has opened up about watching the rest of the series in a "psychiatric hospital in London" to encourage a conversation about mental health.
He said on Instagram: "The Nightingale hospital to be exact. What later I found out is that I had stress induced psychosis.
"Essentially what it is that is kind of like when you get so overwhelmed I think you lose touch with reality."
Niall - who was diagnosed with Asperger's syndrome when he was 10 - noted he experienced hallucinations, and was in the hospital for a fortnight.
He added: "You're not fully aware of your surroundings. You're not safe, you need other people to look after you.
"It takes quite a lot of time to come down from that. But when you do come down from it you really come down. You go into a really deep depression. I was at the hospital for two weeks."
Niall initially thought he was in hospital because of his Asperger's, and he didn't do much media work for 'Love Island' afterwards because he was on "so much medication".
He explained: "When I got released essentially you are then left to deal with 'Love Island' not in the right frame of mind at all.
"I was on so much medication getting loads of side effects, that’s why I didn’t really do any interviews as I was getting really slurred speech from the medication."
Niall noted how he made the "horrible" mistake of taking himself off medication immediately, and he "took quite a long time" to "recover fully".
He continued: "I think it's important if I'm in a position to share my story and journey with mental health and if it could help someone else then it's something I should do.
"I’ve always wanted to be more open with people and talk more about mental health but it's something I've not really been completely open about, as I guess for a period of time I felt embarrassed and shied away from what happened to me."
