Please please help..

Okay so I’ve had an on and off relationship with a guy for almost 5 years. Long story short he’s broken my heart more times than I can count, I keep going back, I’m stupid I know. But this time he broke my heart and it hurts so bad that I’m having a full out anxiety attack. I can’t breathe and I’m shaking. Like the thought of me without him terrifies me. I know the next couple weeks is gonna hurt so bad. I struggle with depression so I’m so so nervous for my mental health in the near future. Please please give me any tips to mend a broken heart. Any distractions? Literally anything to feel better. Please.
