Emotionally, getting social activities will help you. It is good to have quiet time when you need it. You can also listen to motivational Youtube videos while doing house work. Overthinking about PCOS will not help you. Take it easy. Do some research and you will be okay.
Exercise is a good thing too. Walk 30min to 1hour. Go to the mall or market just to get your walk. Seeing different things while walking is good too. You can also start a gym routine at home whichever is comfortable for you.
Food- I just avoid too carby foods and sugar. I use brown/muscavados.
