Hi ShirlisaB!, Welcome to the forum! And congrats on getting married!
I'm sorry that you have to deal with PCOS. I'm not that familiar with it, but I understand that it is not fun at all. If you have any resources on it, I would love to learn more.
Many of the members here journal their progress in the diary section. That way you can get some feedback with your daily routine and be able to track what you are doing and see if there are any changes you can make. Do you have any plan for what you would like to do for exercise? Whatever it is that you do, I would suggest starting off slow to avoid injuries and/or burnout. And as for food, before you make a lot of changes it is sometimes helpful to just track your normal eating (and drinking) habits for a few days and write everything down. Then you can start deciding what to change. I usually don't suggest making sweeping changes all at once because it can be hard to maintain. I normally suggest making small, manageable changes that you can build into your routine. Then as those things get easier, add another small but healthy change.
There is no perfect solution and no perfect journey to get there. The most important thing is to maintain your healthy changes for the long term!
Good luck and I look forward to reading about your progress! And definitely ask questions if you have them.
