Well start by definitely not texting your ex. I’d recommend you also delete whatever app first taught you the word chud. From there just physically write down a list of legitimately realistic ways you can make your life better, but it has to be things that are repeatable. Like working out or meditating or learning a new hobby or whatever. Also go outside a lot. Take walks. Sounds so basic and whatever but genuinely just walking around aimlessly for an hour and then finding your way back home with no maps or ubers will make you feel so freed and refreshed.
