Getting help through the NHS

I was recently diagnosed with PCOS. When I received my diagnosis I was told by my GP that it was common for people to not do anything about their symptoms and that I only need to be worried if I’m trying to get pregnant. I didn’t think much of it and went for a while not bothering to do anything about it. I was talking to a friend of mine who also has PCOS and when I mentioned that I was glad I didn’t get periods anymore they got really concerned and told me that I could be at risk of various types of cancer if I’m not getting a regular period. I was super confused because my GP hadn’t mentioned anything like that to me, but their doctor had warned them about it and gotten them on the right medications. For context, my friend lives in America and I’m in the UK.

So, I go see my GP today to try and see if she can help me get on track with regulating my periods because I’m obviously worried about this risk, but I’m pretty much just told to lose weight and that there was nothing she could give me to help. I understand that weight loss can help a great deal and I’ve never been against it as a solution, but my issue is that I’ve been trying to lose weight for years and PCOS makes it feel impossible. She also insisted that there were zero risks that came with not having a period?

I’m just a bit confused about the different advice I’ve been given, I get that our healthcare systems are totally different, but it really just feels like the NHS could not care less about what happens to me. What do I even do at this point? Can anyone who has gotten help with PCOS through the NHS tell me about their experience with it? Would going private change anything?
