Anxiety

Yesterday marked a week of me and my boyfriend breaking up. I went out, tried to catch some air and have some fun. But after dinner, he had answered one of my texts and we kept talking all night. He admitted he still loved his ex. Me, always suffering from anxiety, went to sleep with a broken heart and my stomach is now feeling really weird. Can't stop thinking about what he said..

Any tips on how to feel better? How to distract myself from these thoughts?
