I can totally relate. The way I dealt with it, and am still dealing with it, is by removing all objects or reminders of the person. Like I trashed, deleted, and burning anything reminding me of her (safely). I called my friends and *****ed to them about it. I doubled up on sessions with my therapist. But the first year of no-contact, even though I initiated it, was the absolute worst. Netflix movies and physical exercise was what helped me survive. I started realizing that the more I thought about her, the less I thought about myself. And that helped me shift a little bit.
