PCOS and changing my lifestyle

So hi, I'm Clarissa and I'm 17 years old.

I found out I had PCOS yesterday and I was told alot.

I've always been a little extra hairy on my face and tummy. And struggled with my cycle a lot, mood, and pain. Now I have to go on a strict diet so I can prevent certain things and improve my overall life. I'm scared and sad because that means I have to let go of a lot of foods and drinks. I'm really scared since I have stuff in my uterus and I have to go on medications to help with things, not only birth control.

Anyone have any advice?
