Given the current size of the mempool and the fees in play at the moment... the OP really has little option but to just sit and wait 
As calculated, the maximum fee they can possibly reach with RBF is only around 4 sat/vbyte total... and there are around ~25-30 blocks worth of transactions that have higher fees than that.
The only other option available would be a "Child Pays For Parent" (aka CPFP) transaction... whereby they spend that 0.00002376 BTC change output in a transaction that pays a comparatively HUGE fee (like 120+ sats/vbyte) to try and push both transactions through, or get the recipient of the ~1.52 BTC output to try the same.
Bitcoin Core has coin control, so creating a transaction that spends that change output should be relatively simple.
