Stoicism isn't being silent about things, and Socrates was kind of infamous for never shutting up.
Really about accepting what you can't change, looking at challenges and setbacks as opportunities for growth, and not living to excess, so lot more in common with mindfulness where you actively monitor and react to how you are feeling, which might include talking about it to peers etc.
Bottling things up and ignoring them is more self-delusion than inner strength, so I think kids talking about their feelings, and not putting up with people being dickheads is a lot healthier compared to alternatives. Took a bit of getting used to, but I think takes a lot more strength of character to confront someone for bad behaviour than it does to ignore them, and kids are a lot more resilient than people give them credit for.
If you want to experience soul crushing frustration, try applying for a job where you apply to a portal, where you have to write half an essay describing your experience, upload a resume that describes your experience, get through AI filters, multiple HR interviews (including stupid questions like 'what is your favourite drink) etc to find out the job pays minimum wage, but you aren't qualified for it anyway as they want a programmer with 5 years experience on a programming language released 3 years ago.
