I do generally use that option but it was sending with way higher fee in the last couple of transactions I did. Like fee up-to 4 USD for 100 USD tx and I moved the scroller to the left and it said within 2 blocks which wasn't too bad, so I sent it with that option and it got stuck.
I'll try the mempool option next time. I couldn't understand what it meant is why I didn't give it a try. So 0.1 MB from tip means it will get picked up as soon as possible? like in next block and 0.2 within 2 blocks?
My current stuck transaction says (9.36 vMB from tip)

I think it is possible that it won't get confirmed this year.
If you look at the past blocks in
https://mempool.space, you can see that the average bitcoin block size is around 1 MB though some blocks can even go up to 1.6+ MB
So if you transaction is at 0.1 MB or 0.2 MB from the tip, it means that should a block get mined in the next few seconds or a couple of minutes, you transaction stands a high chance of getting included in that block.
The longer the next blocks takes from getting mined while more unconfirmed transactions with higher fees keep coming into the mempool, the further your unconfirmed transaction is pushed away from the tip. So having a transaction closer to the tip of the mempool at the time you broadcast it helps to keep your transaction with in the range of the next block in away.
