I am sending it from my jaxx wallet "which changes some other crypto curruncies into bitcoin" to somw website which still waiting the payment confirmation, So I do not know where the dust come from of what does it means!!
What can I now ?? waiting the load to be decreased or ask someone to add it manually on his pool ?? or if there another solution
You could wait a long time until the network forgets about your transaction, or you could try sending a pm to either Quickseller or macbook-air. Both of them have access to big mining pools, and either of them could include your transaction in the next block their pool mines. However they might charge some money to include it.
Another option you might try is creating and broadcasting a Replace-By-Fee (RBF) double spend transaction, Not all wallets can create a Replace-By-Fee (RBF) double spend transaction, and I don't know if your Jaxx wallet can create them as I am not familiar with it. Replace-By-Fee (RBF) double spend transactions and other options are explained in this thread.

A tool and instructions for making a Replace-By-Fee (RBF) double spend transaction are available at this link. Achow101 made the tool, he's a bitcointalk staff member and one of the moderators of this board, so he's trustworthy.

You need to control the sending address's private key to create a Replace-By-Fee (RBF) double spend transaction. This quote from the jaxx website says you control its keys, so it might be possible to create a Replace-By-Fee (RBF) double spend transaction using a jaxx wallet. However I'm not familiar with jaxx so I can't be sure.

All keys are created on your local device and never sent to any servers. This means you have full control of your wallet and Jaxx neither holds nor has access to
