Eat ice cream? haha.
On a serious note. Dealing with stress can be difficult.
But you can talk about it and find the reason why you are stress then get rid of it, if it's getting toxic in your life.
Then adapt to a new way of thinking. Find people you respect and trust and talk to them about how you feel.
Do things are can make you happy, like watching a movie, going on a vacation with your friends and family, eat something delicious, TRAVEL and meet new culture/people, read a really good book etc.
