Why me?

My breakup is so fresh it hardly seems real some time until I wake up in the middle of the night and I'm all alone with nothing but more tears. I'm unable to sleep, eat, or stop crying for 3 days now. My heart aches and I want to persuade him to return but I understand this is wrong also. We've broken up and got back together so many times but this one seems so final on his part. I feel so abandoned and fear my loneliness. These feelings seem to overwhelm my every thought and impede my daily functioning. I want the pain to stop and can't stop analyzing what I did or didn't do to cause this pain. Why is this happening to me? Will anyone ever want me again? Everything in my home reminds me of him - an I'm afraid to touch anything as if it shatters his chance of returning.?. Everyone keeps saying it's going to get better but I'm the one alone with my thoughts and fears at 4am and nothing seems to be getting better.
