You might also need to confront the sense of “protection” that being busy gives you. Does it make you feel more important than others? Does it give you an excuse to say “no” to plans or to avoid some people? You need to find healthier and more productive ways to cope with these feelings, such as finding genuine self-confidence in what you do by creating something you’re proud of, or getting better at calmly but clearly stating your boundaries and needs in relationships.
