Hello guys, I'm new over here, i'm writing a message because my transaction is stuck since more than 2 week, it has been unconfirmed but my wallet send it again. (Mycelium)

can mycelium do 'signrawtransaction' command?
you can try double spend tx with higher fee (if you are the sender)
create unsigned hex rawtx using a tool and use mycelium to sign then push to some nodes
or you can do CPFP if you are a receiver and coin select is possible (choosing UTXO)
if those are not availabe, you need to export private keys and import them to another wallet to do the jobs
