I quit. I can't do this anymore

That bitch AF showed up again to crush all our dreams! TTC #1 for a year and it has been the hardest struggle of my life. The emotional roller coaster is just unbarable. I don't know how couples can make it through years of a life like this. We have done all the tests/surgery( for me I have endo) and everything supposedly is working fine but still NOTHING!! This is supposed to be the happiest time of my life after our wedding starting a family and the constant heartbreak when it doesn't happen I don't think I can handle anymore maybe it's not ment to be for us i don't know. I just want to give up.. Should I start to prepare myself to make different plans for my future that a family is just not in our cards?? I'm sorry I just needed to rant... Feeling so discouraged  :(
