not treating pcos

hey all,

i got diagnosed with pcos yesterday after not getting my period for about 8 months. i've also lost about 30 pounds in the past 8 months due to going off of birth control and having an eating disorder.

now i'm diagnosed with this and suddenly my mental illness became physical and is forcing me to do the one thing i am terrified of- go back on birth control.

what happens if i just don't do anything? i'm so happy with where my weight is now and i am terrified of gaining anything back. i was just starting to reach stability and this feels like a major set back.

can this go untreated?
