I hopes she does too. Have you blocked her on social media and from your phone?
This is tough, it's going to hurt for a while, but focusing back on yourself will help. Take the energy that you used focusing on her problems and focus it on yourself. Think about what you want and need in your life?
Being around friends and family can help too, even if you don't particularly feel like it right now. You will heal from this, but it is going to take time. Bit by bit you will start to feel better if you are taking good care of yourself.
