I can tolerate stress. Though unless I can make it stop, it tends to eat at me: everything reminds me of it and, even after I've forgotten about whatever it is, I can still feel the stress.
It tends to fade with time, though, so at least I know that it won't be as difficult the next day.
Thankfully, I usually can stop myself from worrying about things I cannot control. If that doesn't work, I distract myself with drawing and music. PC doesn't work as a distraction, considering I usually don't care enough to participate in the conversation, if I'm legitimately stressed.
