Feeling hopeless

Hi ladies having a awful day today so needed to post to vent out some of my feelings! I feel so hopeless today like I'm never goin to have a baby....it's been 3 long years of trying without any success at all, we're classed as unexplained which is frustrating! We're still both only young 26 years old so don't know why it hasn't happened for us so far.....,anyone have any stories that might help give me some more faith it CAN happen for us would be most appreciated please???
