So frustrated!

This is my 3rd month TTC and I know it takes a while. I'm 28, have PCOS, and Metformin hasn't been helping. I can't lose weight no matter what I do and everyone around me is getting pregnant with ease. I seriously just want to cry. And the support found on here is rather lacking. My bf tries to be there but I don't think he can really understand. :( OK. Rant over.
