Having talked to many traders, and in my own experience, taking a "trader circuit breaker" helps to interrupt bad habits. Sometimes traders are trapped in a vicious feedback loop of bad trading => bad results $ => bad mindset => bad trading and stopping trading helps to halt that pernicious loop. But you really need to take a step back, no trading even in sim. Is a detox therapy from trading.
Then some clarity comes and you will see clearly what you were doing wrong. So take some days completely off trading, then use your time watching other traders recaps, watch / re-watch some success webinars, review your rules and your journals.
Then come back to sim and follow up your discipline, make a daily checklist of your rules and follow up your rules compliance every single day. You will want to define a period of acceptable rules compliance and discipline, that could be a week, some weeks, a month, etc. before coming back to trade your account. Just be mindful that old bad habits don't disappear from overnight. The same is with good habits, it takes some time to get rid of bad habits and it takes some time to build good habits. Your goal here is to use your rules to govern your trading behaviours and practice those rules and behaviours until they become an automatic response, a second nature. Then, after your reach your goal of rules compliance for the period of time defined by you, go back to trade your account, starting small, and define rules to increase your risk/trade or share size.
And don't believe those telling you that sim doesn't work. We build bad and good habits in sim and we need to come back to sim to get rid of the bad habits built in sim. If you are not able to be disciplined with your rules in sim you won't be disciplined trading your account.
