Is anyone else sick of the heartbreak?

Each month I tell myself, "This is going to be the month!" And each month it isn't. And my SO tries to tell me that's it's okay. It's okay. But it really isn't. He eats a family too, but I don't think he understands how much it truly means to me. Now ta to the point where when he tells me it's okay I get so mad. Cause it's not. It's not ok anymore. I already suffer from depression, which I have handled for the most part. But when it's my time of the month, or I get a BFN, I get so depressed. And he doesn't understand. He says we'll try again, but I'm so sick of trying to only be let down. I'm not going to stop, but it's getting so hard to deal with now...
