how does one achieve a negative balance 🤔

In my five years of trading, I have lost 90% of my account due to two mistakes. In 3 hours, I made a mistake and did not put a stop loss. I thought I had put a stop loss. The second mistake was that I left the account due to overconfidence. I came back three hours later to do something else and saw that what was supposed to happen had happened. Although I never exit the market while trading, what a cruel twist of fate. My account, which I had built up little by little over the past 5 years, was wiped out in 3 hours today. My intention is to tell you that you should not make the same mistake as me. Sometimes, the funds you have built up little by little can run out in an instant. Be careful when you see this post of mine. This is my intention. I don't want you to suffer any such loss. Be well. Everyone, pray for me so that I can get back on my feet again.😭$
