It should be dropped from most mempools soon since it's so low, in which case your wallet balance should return to normal. If your transaction fee were higher, it would bounce around the mempools for ~2 weeks before dissapearing. the 'v' stands for virtual. combining utxos when making a transaction is good for the overall network, but is larger in bytes than splitting a utxo. so this data is given a discount, where a byte of witness data only counts as 1/4 byte when paying fees. so they call this 'virtual bytes' to differentiate from actual transaction size.
