There are three options for you:
The firstUse CPFP if you are the receiver, and that the receiver wallet can spend unconfirmed transaction (like electrum). All you need to do is to send the unconfirmed bitcoin to another address on the same wallet, but with a very high fee. Using around 270 sat/vbyte will be good for the child transaction. But, because of the high fee, I will not suggested this for now.
Second oneYou can make use of paid Accelerator like ViaBTC, but also not still recommended because of very huge fee that will be paid.
ThirdI will recommend you to make use of this third option. Make use of free acceleratator, most free acceleratators are fake, but
ViaBTC still do work perfectly. I have tried to accelerate it for you, but not working, it do take 100 transactions per hour, try to make use of it like 5 minutes to the start of an hour to like 10 minutes after, likely it will work around such time.
