Do you think it's at all beneficial to watch/talk about things that trigger negative emotions?

I don't like having anxiety or my stomach in knots but I've noticed the more I confront my insecurities and mistakes in uncomfortable manners, the more I can see clearly (given the fact I feel so nauseated that it almost is conditioning me to only think of consequences in bad situations). I don't like the feeling obviously since it is barely a step behind a panic attack, but in general, I'm wondering if it's helping me much or if I'm stressing myself over something that'll be disregarded because it isn't constant.
