A simple question with no easy or real solution. You are the only solution to get over the breakup - there are several things you should do. Lose your ego and express your feelings to the person one last time. If she ignores or ditches you, you know there's nothing in your control and you did your best.

Recognize that it is normal for you to losing sleep and appetite and focus from doing anything. Everything is just bland for you. That is the way it is.

Now that is done, reflect on how you lost so much self respect to chase this girl and how lousy you were. But you ain't really that lousy. You were doing fine before meeting this girl. How did you end up here? Is she the only girl that can give you what you want? Are there other people that care about you? Are you gonna neglect them?

Now, work on yourself, cry it out, delete the contact and social media. Write down any thoughts or memories and toss it away. Meet new girls, go learn something new, go work yourself out.

You should be able to get yourself out of this in 1 week to 3 months time.
