Can someone please help me out here?

I have like 3-4 transactions in Que or Pending in MetaMask and I cant do anything with them I've looked up videos on what to do and i've tried to update the nonce with more gas (even though i've set it to fast gas option everytime.) And I cant do it because of the fact that Etherscan.IO doesn't show that theres a transaction yet. But nothing is going through. Will I lose all of the ETH in this wallet due to this? Like since theres not very much ETH in the wallet will I lose whatever is in there after the gas comes out for the next transaction to ATTEMPT to be processed? I'm so tired of these high gas fee's and slow transactions its getting so frustrating… EDIT: I figured out how to get the NONCE number and have sent a transaction to the same wallet address with an updated GAS fee of 116 GWEI and like 55K gas limit and its still not going through I do also have one REPLACED transaction that has been pending for like 20 hours now that might be causing this but as I already REPLACED the previous transaction then that one should be NULL right ? What a freaking nightmare just to buy some NFTs…
