Mason Warwick was found at home in Brighton, East Sussex, and was rushed to hospital by paramedics, but he could not be saved.
Mason's grief-stricken parents Kelly and Daniel Warwick said: "He was our amazing special angel."
His death is not being treated as suspicious and the coroner has been informed, said police.
A family member said: "He was the loveliest sweetest boy.
"He was happy-go-lucky, really polite, and loved by everybody.
"You couldn't' ask for a better kid."
Mason's grief-stricken parents have spoken out as the community rallies round the family.
A GoFundMe page set up for the youngster claims he was a victim of bullying.
The page states: "As most of you know this beautiful little boy Mason took his own life on Thursday night due to nasty bullies.
"He was such a loving caring young man with a heart of gold.
"His parents are struggling with the loss off their little prince as you can imagine and would love anyone to help raise a bit of money to help them at this sad time.
"Money won't bring that precious boy home but will help the family a little. Rip Mason."
