Infertility causing depression

Kelsey • Ttc #2, mom to 18 month old, wife, male fertility issues, going for iui/ivf soon!
Have any of you ladies really become depressed when you get your bfn? I feel like I will never get pregnant. Been trying for a year. I go to the fertility doctor on the 6th but I feel like even with that is gonna take more months that I don't want to wait. I feel like emotionally I can't handle this anymore. Af showed today and I have been crying and crying.
