Struggling with Schizophrenia Diagnosis and Treatment

Unsure how to feel about diagnosis and future treatment. So this year I was diagnosed with paranoid schizophrenia and I don't know how to feel about it. I've had symptoms (prodromal and acute) since I was like ~10-12, and I've spent my whole life thinking it was normal, but with it getting worse recently and not being able to hide it (in a relationship now and living with my partner) I've realized how badly its affected my life and ability to work, make and maintain friendships and even tell the difference from reality and fantasy sometimes. The psychiatrist told me there's no cure, and only medication can help, however with my ED habits, the fear of weight gain currently outweighs my ability to recognize how serious this is. I guess I'm just overwhelmed by it all and needed to rant. If you read that far then I appreciate it and honestly any advice would be great. 🙂
