Tragic Dale Winton became so depressed and ill in his last years, a petrified neighbour used to check up on the much loved star every day to make sure he hadn’t killed himself.John Wenzel, who lived two doors down from the Supermarket Sweep host’s US home, revealed that just six weeks before his death Dale said he could not get over a love split and admitted: “I have a broken heart.” As his happiness deserted him Dale suffered physically too, with breathing problems caused by heavy smoking and crippling shoulder and back pain that left him struggling to walk.Things got so bad for the TV host he hardly left his house, but some locals who spotted him out dubbed him “the man with the deformed back”.John, 60, told the Sunday Mirror: “When we last spoke it was about six weeks ago - and Dale was in a really bad state of mind.“We spoke about politics for a bit, then he mentioned his depression.“He said he was still devastated by the break-up of his relationship and couldn’t get over it.He said ‘I have a broken heart’.“But this was not new - his depression had been causing him problems for the last three years.“ Last night police were still probing the death of the former BBC National Lottery host, whose body was found at his rented London home last Wednesday.Dale was just 62 years old.His death is being treated as “unexplained”, but not suspicious.John said: “It is so sad.It is so hard to take it all in.Dale was such a great guy and deserved to go on living.” He and Dale became neighbours 13 years ago when the star bought a three-bedroom house in a gated community in Sarasota, Miami.It is believed Dale had been living between the UK and Florida for the last 15 years, but he chose to spend the majority of his time in America to escape the glare of publicity.John said Dale loved to potter about his US home close to a golf course and could often be seen riding his bike around the neighbourhood.Speaking from an armchair on his front lawn, father-of-three John said: “We have talked and joked with each other so many times over the years - but I always knew it would not last.“I always worried that Dale would take his own life one day, just like his mother.“In fact, I always thought he would not die of natural causes." He said: “He just could not get over this guy.“He really must have been in love with the man and I think the depression of his break-up is what killed him.Every time we spoke over the past three years he would always talk about it.“He was such a happy guy at first, but then I saw the life sucked out of him.“I’d say ‘Hey Dale, how’s it going?’ And he would respond with stuff like, ‘Oh I’m depressed, it is all too much’.On some occasions, he’d go back to being his old self and scream, ‘I am fabulous’ as he cycled past me.But then I would see the happiness just drain straight back out of him again.“I tried to tell him to get over it, but he just could not do it.” Dale’s mental deterioration was mirrored by his physical health.John said the star beca
