Play, and you will gradually accumulate experience; you will earn it back.

I am thinking about whether to give up or not, I have already lost over 500 million on stocks and futures.
My job has a relatively good income, but working to earn money and then pouring it into the trading platform makes me feel incredibly foolish. Should I go back to stocks now? I am really depressed. Is there anyone else in a similar situation? Please give me sincere advice. If I give up investing now, I will regret the money I have lost. But continuing also feels too hopeless.
