Referees are coming under increasing scrutiny as a result of greater media focus as well as social media outlets, such as Twitter.
Halsey, who retired from officiating at the end of the last Barclays Premier League season, believes more needs to be done to support his former colleagues.
"There is no hiding place on the field and you have to be mentally tough. But it also follows you off the field more and more now and it can destroy you," Halsey said in his autobiography which is being serialised in The Sun.
"I do feel that referees should get more help to cope with the increasing level of mental strain.
"In my view, given some of the episodes of recent seasons, it will not be long before a referee has a nervous breakdown.
"I also believe that if we do not do something to help referees with mental health and stress issues, then we could see a suicide."
Halsey was the victim of two abusive tweets 12 months ago after officiating in Manchester United's 2-1 victory over Liverpool, sending off Reds midfielder Jonjo Shelvey before awarding United a penalty, which was scored by Robin van Persie.
The tweets, both of which referred to his throat cancer diagnosis in 2009, were widely condemned by other Twitter users and while Halsey received support from Premier League managers and friends, his former bosses were a lot less forthcoming.
"I got little from my bosses apart from a call from Mike Riley, the head of the PGMOL, and one from the Select Group manager Keren Barratt asking if I wanted to come off my next game at Southampton."
The simple fact of the matter is that refs are going to make mistakes. Yet if you watch any pundit they never ever ever give any leeway. You always hear the same lines "the ref should have seen that", "a good ref has to give that". As a player I was horrendous for giving refs grief, however when I referred a few matches I soon realised how hard it actually is. I firmly believe that all senior players should be made sit the referees course and ref some amateur matches to get a feel what it is like. It would truly change everyone's perspective. How do we improve refereeing decisions? It's simple technology similar to that which is used in rugby. If a referee commits suicide due to abuse received because of an incorrect decision the responsibility lies with their employer. This abuse could be stopped so easily it's farcical that it still isn't implemented!- anfieldrap1985
