Stress is common when one is suffering with PCOS. Given that there are a myriad of issues associated with the condition including weight gain, irregular menstrual cycles, skin problems and infertility, stress is bound to occur, which again makes things worse.
Furthermore, chronic stress can itself lead to anovulation and irregular menstruation, which also means that it is associated with fertility issues. Again, excess stress can cause a spike in cortisol levels, a hormone that increases sugars in the bloodstream, leading to many other health issues.
The best way to relieve stress is by indulging in calming techniques such as yoga, meditation and massages. Do not put too much pressure on your mind and give it time to relax.
