Defeated..Disappointed..

Well AF showed up. I was praying so bad for it not too & to get that BFP. I feel unbelievably sad and idk. I'm amazed that some people have been TTC for yrs and not give up. I truly feel like giving up and it hasn't been but a couple months. I sit there and do so much. Preseed, bbt, opks, smep. And then nothing. And then i even have started not to pay attention whatsoever to symptoms so i don't over think them like i did the very first month. I just don't know what to do. Why is this so hard?
