Executed over $300k in trades over 5 years just to break even.

Pretty much what the title says. I executed over $300k in trades (not account value) since 2021 and after reviewing my overall performance and after some recent losses I have essentially broke dead even. Account value is around $125k. Thats basically all the money I've saved over the last 4 years of working my first job outside some money in a 401k. So it's not all bad, I could've lost it all I guess, it's just that I essentially got the same results as keeping it in a regular savings account but with all the added stress of tracking the market every single day for the last few years. Which took a toll on my mental health, and in some ways my physical health as I lost motivation to workout these last few months when certain plays didn't work out and I was drinking more and eating like garbage. I'd say at the peak of my account's value I was still underperforming the S&P by about 60% anyways. It made me realize just how much of it was gambling, really the first 4 years were stupid gambles on stuff I barely even remembered doing. Some names I pulled out of like NKE and PYPL before losing money which would've been brutal at the current levels. I sold a few of my biggest recent losers though and just threw it into the S&P and Microsoft, I still hold some Adobe (only one I'm still negative in) and Novo Nordisk but it's not much. I was panicking pretty bad initially but after watching them continue to fall since I think I made the right choice, sometimes you have no option but to cut your losses. The account is basically 50/50 MSFT (cost basis of $398) and VTI (cost basis $350) now, with some left over in the other two names, I truly believe in the oral semaglutide Novo has and Adobe is just beaten down with the rest of SaaS, I don't see much wrong with either businesses. But other than these I'm done buying single stocks probably forever outside of the Mag6 (I don't count Tesla) as wheeling whichever one is beaten down/has the cheapest multiple usually seems like a safe easy way to make money and then rinse and repeat, considering those are the stocks mainly holding up the S&P anyway. I guess I already know the answer but for someone like me it seems index funds are the obvious choice for long term growth. Even if I were to beat it the stress it was putting me under was getting to a point that it was ruining me as a person. I wish I started index investing sooner especially during the 2022 dip although I'm young and didn't really have a ton of money back then anyways. There were a few names like MU, GOOG, INTC, etc... that had I held I would've almost doubled the S&P performance but that's my (and I feel probably most other traders) fatal flaw is that in order to really outperform its all about timing. And as the old saying goes time in beats timing the market pretty much always. The emotional part seemed to be my issue more than the analytical part and picking the right names because for the most part I was but I was always selling right before they ran up huge. With indexes there isn't really that worry of needing to enter and exit at the right time I guess. Idk what I'm looking for in terms of advice because I think I already got it sorted out, I'm just sharing my story as it was a valuable lesson for me and seeing just how much money I had traded in that time to make essentially no gains was astounding to actually look at. It made me realize that I could've lost so much more than just opportunity cost or probably actually went into the red had I kept going. My advice to anyone who doesn't really know what they're doing but thinks they can beat the market, even if you think you do, is to just index and chill, maybe play around with 10-20% of your account but going all out on single names rarely pays off, no matter how many people on Reddit claim to have become overnight millionaires. If the biggest brightest minds on Wall Street can't do it odds are you can't either. I'm willing to bet there's a lot more people like me you just don't see them talk about it or post about it online due to embarrassment.
