Tough luck if this was really the first time you've used Bitcoin. Whoever sold you the coins obviously skimped on fees, you should have ensured the seller would have used enough fees to guarantee a reasonably quick confirmation time, especially since the buy was worth over $2,600!
Nevertheless, in light of the current network with almost 100k txs, you can still try a few things:
1. Ask the seller (the guy who sent you the coins) to do an RBF transaction. You could offer to ask him to share the fees, taking some from your tx.
2. Try and submit your tx for confirmation at
https://pool.viabtc.com/tools/txaccelerator/. Your tx meets conditions there, but they only open for 100 submissions every hour or so, around the hour. You can also register and try at antpool.com/user/prioritiseTransaction.htm?m=savePrioritiseTx, though expect a long wait.
Also, confirmtx, mentioned in posts above, has been found to be a scam.
