Note that stoicism is NOT rejecting and ignoring your feelings. If you feel bad about something, that too is a fact that you have to accept and deal with in the best way possible. Stoicism is about keeping your head up in the face of adversity, and not about becoming a hardened robot capable of taking any punishment. I think a lot of people on HN might get this wrong.
Personally I don't see much evidence that this really was the case in the golden era of Stoicsm. Freedom from all passions was not the same as removal of emotion, but it was very close to it.

This was exactly what Stoics of the old saw as ideal and this view was propagated in stories. Epicetus was a cripple and according to Origen his leg was broken by his master.
>Epictetus' master one day was twisting his slave's leg to help the time pass. Epictetus said calmly, "If you go on doing that, you will break my leg." The twisting went on and the leg broke. Epictetus observed mildly, "Didn't I tell you that you would break my leg?"
The story of Gaius Mucius Scaevola was also propagated by stoics. Mucius kept his hand over the fire without indicating any pain while it burned.
