Feeling depressed. PCOS

I have a feeling I have pcos. Everyone is telling me I have the symptoms and I even knew I had the symptoms. I made a doctors appointment for tomorrow but I just hope I don't have it. I've had enough bad things in my life and if I can't have kids then I honestly don't want to live. I feel like I'm useless. Can women with pcos please tell me their symptoms and the struggles they face with it. I would really like to know...thanks in advance..
