How do you ladies do it!?!

I have only been ttc 4 cycles and got AF again today, I want to give up!!!!! I want it so bad I feel as if it's impossible I will ever get it 😔 some of you ladies have been trying for so long and I know I sound ridiculous to you, but I don't know how you do it. My worst fear was always being unable to bear children and though it's only been a few months it's eating at me that maybe my worst fear has come true.. I just would not be able to do this for years it's ripped me to pieces with fear the last few months
