Being stoic doesn’t mean not expressing your feelings.
Issues that someone would have to bottle up because it introduces entropy in their feelings about life might be a non-issue/non-existent to a stoic. i.e. why get angry and express my feelings if someone that cuts me off on the highway, when I’ve learned not to care about such events? There’s plenty of other things a stoic can express their feeling about.
The Discourses of Epictetus
> According to its teachings, as social beings, the path to happiness for humans is found in accepting the moment as it presents itself, by not allowing oneself to be controlled by the desire for pleasure or fear of pain, by using one's mind to understand the world and to do one's part in nature's plan, and by working together and treating others fairly and justly.
> Stoicism teaches the development of self-control and fortitude as a means of overcoming destructive emotions; the philosophy holds that becoming a clear and unbiased thinker allows one to understand the universal reason (logos).
> A Stoic of virtue, by contrast, would amend his will to suit the world and remain, in the words of Epictetus, "sick and yet happy, in peril and yet happy, dying and yet happy, in exile and happy, in disgrace and happy," ...
Happiness comes from the attainment status and progress, and those two things tend to be correlated. That's why beating a video game level or getting an award or promotion makes you happy. it does not come from reflecting on failure or any abstract philosophical belief/teaching. The idea that happiness is encoded in failure seems ludicrous unless one means not repeating mistakes, but that is learning , which is not the same as happiness as an emotion. Not a fan of stoicism either. I think people should express how they feel. Bottling it up only makes it worse later.
