Hope you are still trading, you're on the right track.
I'm in Sydney Australia too and I find trading the ES euro open (5:30pm-7:30pm AEST, which is 2:30am-4:30am) to be the most accommodating time. It just feels like I'm working OT, and doesn't affect my personal life too much. Additionally, the market is not overly thin or thick and the price action moves a lot slower, giving you more time to make decisions.
Watch Jason Davies Jigsaw videos and also FuturesTrader71 videos from the webinars page here. I trade similar to the advice given above - delta, tape and levels (breakout, range fade, pullbacks) and having said that, breakouts are the hardest to trade due to the gaming, I have personally found. You might have more success trading range fades and pullbacks first.
Also don't give up, if you've looked at the tape and your first response is "it's too hard" then you are failing yourself before you've even started. Nothing is ever too hard. If someone else can do it so can you, giving up is the lazy mans option.
I noticed that you are also doing well but a rogue or revenge trade day here and there would wipe you out. To stop this from happening, I found that by visualising "where" you are willing to trade and what setup you are willing to trade at certain levels and only giving yourself a few ticks of room to do it, will help you become picky. I know for a fact I miss out on 2 or 3 good trades a day because they never reached my "trade area/level" but at the same time, I knew if I took trades at those levels next time, I will get burnt at some point more often than not. The fear of missing out is a strong one, you need to fight it.
Anyhow, the demons you are experiencing are the same ones I fight every day, I've gotten better at controlling them by setting rules for myself that are very clean cut with no exceptions. No exceptions is the key, once you let yourself go once, it'll only take a few more trades before you think you're better than your rules and you let go completely - we know what happens after that.
