With 500k... You could still invest that in a dividend etf. It will give you a constant payout of around 20k per year.
That is not bad if you are able to get some Minijob also and it will still grow slowly over the years. But say goodbye to be a millionaire.
That is what I would do personally and is no financial advise. You know your life better than me. Investigate on your own.
Stop trading and collect your wits. Asking for trading advice here won't make anything better. Keep what is left of your money and leave it invested while you find a way to make more without depending on your savings. Once you get on your feet, go back to market with a much smaller amount and teach yourself better risk management until you are confident enough to slowly increase your positions. And find your wife a boyfriend, just in case.
