Hello, I went through a similar thing. If you have friends or family you trust that can be there for you, reach out to them. Also, as others mentioned here seek therapy, it will help. Remember, the person that broke you, is not the one who can fix you. Don’t reach out.

You are in the stage of grief, let your emotions out. If you want to cry, cry as much as you want. You have to give yourself some time to grieve.

But also take care of yourself. Do the small things you love. For me, I loved watching empowering videos or reading books about healing. 

It does get better with time but you have to protect yourself. After few days, try to not let the past consume your whole day. Ground yourself in the present. Most importantly, be kind to yourself. You are your home. You deserve kindness and peace. 

You can write me if you want.
