Devastated

Yesterday I found out my boyfriend isn’t physically/sexually attracted to me. He never was, it isn’t something that he lost over time. He wants to work on the relationship and try to fix it all. I’ve always had body issues and I hate the way my body looks. I’m trying so hard to lose weight and get to a place where I’m happy with myself but hearing this just shatters me. I’m not sure how to get past this.
