There are two options. You can attempt a Child Pays For Parent transaction in which you create a transaction spending from this unconfirmed transaction. That spending transaction will need to have a transaction fee that is sufficient to cover both the spending transaction and this unconfirmed one.

Alternatively you can contact the user macbook-air and ask him if he can confirm the transaction for you. He is in charge of f2pool so he has the ability to do this.

It depends on your wallet. What wallet are you using?

That is your address.

I meant what wallet software are you using? blockchain.info?

[mdllbm]

yes

[socks435]

yes

I think better to give more information about your wallet if you are using coinbase, xapo, electrum, blockchain, bitcoin core,
What wallet do you use right now?

[achow101]

yes

He responded to my question; he is using Blockchain.info

Unfortunately blockchain.info does some really stupid stuff and makes it difficult to do any advanced tasks, so you cannot use it to create a CPFP transaction.

But can't OP do it by importing the address to another wallet and create the CPFP transaction from there?

Edit:
Ah. Looks like the transaction got confirmed. Gratz OP.

I've never understood how you choose a pool you want to confirm or is it just randomly gets confirmed by a pool. When one confirmation doesnt confirm and the next and so on what is to say the 5th confirmation will confirm. Who decides if a pool's ownders do not decide than who? That really confuses me cause theoretically a transaction can get stuck forever by this mechanism.

The pool software decides whether they want to include your transaction in a block. This software can be tweaked to include or exclude certain transactions.
