when you say "i see that blockchain resend the transaction automatically", do you mean that you sent the transaction from a blockchain.info wallet? Given the telltale 120 sat/byte fee, I'd guess that this is indeed the case...
If so, your only option is to contact blockchain.info support and ask them to stop rebroadcasting it. Until they do, it won't drop from the network and your coins will be stuck.
In any case, I doubt it will confirm, because it has an unconfirmed parent anyway...
