I dipped my toes into individual stocks and it went like hell.
Bought AMC during that whole Gamestop period for maybe $15 ($1000 total). Went up to $25 I think and that's when the fuckery happened and I couldn't sell. I think I got out and it was $10. Took a 1/3 haircut there.
Left it in that account and eventually bought PLTR around $20. Went up to $25 and I'm like fuck yeah, let it ride. Fell to $10 and I sold. Was down another 1/3 of my initial investment ($300ish)
Started more actively trading it and was able to buy back in at $6. I don't remember the exact details, but I eventually sold it to where I was only down 50% of my initial AMC investment ($500).
Decided to cut my losses and never actively trade again. Even though $1000 was 0.01% of my portfolio, it still hurt.
Had I kept holding that PLTR though, holy shit.
