I want to give up

I'm 30, pcos w healthy bmi, hypothyroidism and one blocked tube. I can't ovulate on my own and it took almost a year to get a clear answer on that alone. Found an RE...1 month clomid-BFN, 2 months femera-BFN...next he wants to do shots and iui. Over the last year I have lost myself in this and it feels like it will never be my turn to get a bfp. Everyone around me is pregnant and having babies and I'm broken...at what point do I just give up? I feel so alone all the time...
