PCOS and endometriosis make me feel like I'm broken

I was diagnosed with PCOS when I was 16 and diagnosed with endometriosis when I was 18. Ever since I found out I had these diseases, I just feel like something is wrong with me. There's no cure, and I'm scared I'm going to be sick forever. My boyfriend and I aren't in a rush to have kids since we are both still young. He's been really supportive. But I'm still feel really worried about my reproductive health. Does anyone else feel this way?
