I’m 16...17 in a few days

I’m 16..17 in a few days.

Today I got told I have pcos.

Today I got told I had a very low chance of ever being able to carry a baby.

Today my heart broke into a million pieces.

Today I got told that if I ever wanted a baby my best bet would be to start tying for a baby now because in the future I might not ever be able to carry a baby.

Someone help. How do I come past this?

My boyfriends being so supportive but I’m so scared it’s going to change things.

Iv been with him 4 years on my birthday, I’m so scared that it’s going to change things.
