Sick of PCOD. Help!

I'm 27 years old and had been diagnosed with PCOD five years back. My period keeps stopping once in a few months and I need to be on tablets by gynecologist to get my period again. I'm sick of it 😞😢 I have not got period again and I know it would be because of weight gain. I keep feeling stressed if I have gotten pregnant or if it is PCOD. Has anyone got any suggestions on how to lose this weight and get rid of PCOD. My face is also having scars around the nose because of this and constant headache as well!
