I made in total 1 dollar

I started day trading 3 days ago and it was the weirdest and hardest days of my life. I live in van so I wake up at 5 do my analysis, drink coffee and look at the news(I use WSJ). I am trading with 5K cad and after 5 6 hours of hard and very stressful work and losing and earning money I madeeee 1 dollars 48 cents net profit ☺️. I actually am thinking quitting while I can because it was very very stressful for me! I only trade Nvdia and I trade it with 50 shares always(margin account)!!!

What should I do next?
