19 with PCOS. No one told me till now!

I’m 19 and I just recently found out I have PCOS. What’s even worse is that I’ve had it apparently for a while now but no one decided it was a good idea to tell me. My mom has known this whole time and didn’t tell me because she thought I would be “too sensitive about it”. I always knew something was wrong with me but she would always play it off as it being my fault. Like she would say I’m fat and that I needed to lose weight but even though I tried I couldn’t keep it off and she would just say I’m lazy. Could any one give me a few helpful tips on how to over come this and help me get started on helping my symptoms and mental effects of this. I have no clue where to begin. And I just want to be healthy again. I know it’s something that has no cure, but what can I do to help myself? I am on birth control but it doesn’t seem to do much for my hormones. I still have irregular periods (either incredibly light in color and in flow or lots of time just spotting for a few days and 1-2 days either early or late). I’ve heard the light kind of pink color period is low estrogen is this true? I thought the pill boosted your estrogen? Do you have work out tips? Healthy eating tips? Is there a big chance I have infertility and how would I get that checked? Also I’ve heard it can be the reason why I have so much trouble falling and staying asleep. Do y’all have tricks to get better sleep?
