My ex [23F] ghosted me [23M] for the first time, her silence is hurting me, how can I deal with the unhealthy obsession?

My ex, never ghosted me during the break ups, she said she doesn't want me anymore due to repeating the same bs everytime, we used to talk, share pics, and update each other even during break ups. A week ago, when we had a fight, and it was the moment when she went cold-turkey, not answering me at all. I keep calling her, she blocks every number, she ignores all my messages, she responded to my friends, telling them: "all that being said, I appreciate you reaching out but I'm really done with his shenanigans this time, no amount of talking or convincing changed his mind and now it's all too late", Note, that she broke up with me many times, and I got with her back many times, I seriously love her so bad, and her silence is truly suffocating me, how can I deal with such intense feelings?
