I Wanna lose hope but I also don’t!!!! Help!!!!

So when me and my boyfriend started trying I knew it wasn’t gonna be easy I have PCOS and my periods have never been regular. So we decided to go to the doctor.. the first doctor who I’d normally go see told me “you’re to fat you’ll never get pregnant” the second one that I tried to get in with wouldn’t see me because we haven’t been trying for 2 years and the 3rd one who I’ve been seeing for about 2 weeks or so wants me to lose 12-17 pounds before she’ll do anything. It’s so hard for me to lose weight and I really just wanna give up and no even try anymore!!!! Encouraging words are welcome please and thanks. Just really need some support right now!!
