24 hours of no contact. I feel so numb

We broke up 2 days ago now but the last time I contacted her has now officially been 24 hours. I don't know how to keep going, it feels like every hour ticks by slower and slower and the more the time passes the more that it hurts.

How could she be so okay with losing me when just a month ago she was talking about how she wasn't going anywhere and just last week we were on a date holding hands together and everything seemed perfect? I can't stop thinking about her every minute of every day and every little thing reminds me of her. I want to cry but I feel so numb. I wish I can forget all the memories, it's nothing but a curse. I keep hoping she will come back and change her mind but a part of me feels like it's over.
