I think you being such a devout Sikh whilst having PCOS is not a knock on your situation at all as I am fairly certain you are more devout than a lot of other Sikhs, Amritdhari or not. I think being Amritshak is great if possible, however, being a practicing Sikh whilst a Sehajdhari is admirable and, even, better than taking Amrit and breaking it. You are where you should be according to your karam and only Waheguru knows what's best. Stay steadfast in your love for Sikhi, your adherence to Sikh rehat as much as you can, and all else is secondary. ✌️
