My bitcoin transaction does not exist in blockchain.info nor does it exist in any tx accelerator
Did you maybe use a very low fee? In that case your wallet may have rebroadcasted the tx while other nodes dont relay it because of too low fee. 

I expect you have the mnemonic to recover the breadwallet saved somewhere. Maybe try to deinstall breadwallet and reinstall it using your mnemonic and see what it then shows?
