Your brain (and even your body) can get a lot out of talking through problems. In fact, research from U.C.L.A suggests that putting your feelings into words can diminish the response of the amygdala, a part of the brain responsible (among other things) for emotional responses, including fear, anxiety, and aggression. This is why, as time goes on, you can overcome stress by talking about your experiences with peers.

For example, if you are homesick while at school, your daily life can be emotionally overwhelming. However, as you spend more time at your campus and talk through your issues with peers and friends, these feelings of anxiety and fear of being away from home can start to subside.
