Just got broken up with after a year and a half of being together::

What are some things you used to get over an ex? Bc I’m been crying nonstop for the last two days and haven’t eaten anything. I feel like my heart has been stomped on and my body image is so bad right now. It was so out of no where, he broke up with me over text on my great grandmas bday, she passed away two months ago, and he still wants to be friends but I love him too much. I need to fix it. But I can’t. So please any advice would be appreciated, I just want to feel okay again.
