Hi 👋
First of all, breathe in and breath out for 10 seconds. Now tell yourself why are you mad? Is this logical? Or are you just overreacting?

See that face ☝️. That is what I am trying to achieve so here are some things you could do and if those don't work. Just listen to cheap thrills (Sorry I just love that song).
Read the chats in unipeeps, they are so funny.
Imagine yourself bald.
Make a funny chat(that works when you are sad too)
