I've gone through several periods of intense stress that actually did make me ill, but seeing things from a Stoic perspective (focus your energy on things you can control and just note the uncontrollable factors without getting emotionally invested in them) has helped me a lot.
From the video, what I took away is that stress can be bad for you if you see it as bad, but in the right context it can be beneficial. Unfortunately the TED talk didn't really get into any how-to advice. To become more resilient when things are going all to shit, I think one would have to get into the habit of interrupting catastrophic thinking and replacing it with more pragmatic thoughts on how to solve specific problems, then following through with an appropriate action.
