help – ETH pending transactions

Hi,

I had a pending transaction on my ETH account, I tried to cancel the pending one by sending a transaction to my wallet with 0 ETH and increasing the fees, but I guess that I did something wrong and now I have like 6 transactions pending and nothing works, even sending a transaction to myself with the correct nonce.

is there anyone that can help me get rid of all those pending transactions? My address is 0x2B8A442CE4D5d9d2b928484f16f0B9F2D75434a3

thank you
