Tip number one, dont google pcos a lot when you first find out you have it. It leads to a lot of overthinking, anxious thoughts and even getting your head into situations that may not happen to you. (i learnt this from experience!)
Tip number two, focus on what you can do now to help yourself in the future. E.g. kids, if you want them and have weight problems then maybe think about losing weight because it can help in the future, plus you dont want to have more health problems.
I have PCOS since i was 16, im 26 in a couple of months. I found out I had it when i didnt have a period by the time i was nearly 17 and had other issues that are a side effect to pcos. The doc did blood tests and scans and found out i have it. I've been on the pill since and i've had about 2 or 3 scans over the years to see how bad it is. There is a chance said by the docs that i may not be able to have kids (this devastated me since everyone i know knows that i want kids and always have done), but with ivf available, pills and all sorts i shouldnt give up hope yet and who knows what will happen when i try to have kids so i have to wait til then. I am really overweight and i have tried for years to lower my weight but with no luck, last year i tried slimming world and since starting it i've steadily been losing weight. I've lost 2 stone so far and still losing, so its working and my docs are happy that i've found something that doesnt involve a fad diet cos the quicker you lose the weight the more chance of you putting it back on, you need to lose it slowly and steadily to keep it off and you have to want to do it too. If anyone wants to talk or ask me quetions then feel free to. I tell you now i hated the ulltrasound scan, i felt horrible afterwards.
