Break up advice pls 💗

How to recover after you broke up with your toxic ex yet your still heartbroken and it was 3 months ago. Yet he’s moved on and already in another relationship 😓 I know I shouldn’t be sad bc it was toxic, manipulation and abusive relationship but for some reason it still hurts. Yet my support group says be happy you dodged a bullet before it really broke the skin we were together 6months. I have the worst anxiety hate going out alone scared I might run into him or his family even cry if I drive past him 😓 what’s wrong with me
