Vent session

I don't know why I get on here. It just makes me depressed. I see about 20 new positives a day, and I'm incredibly happy for everyone of them but I get sad too because it reminds me I'm not one of them. I want a baby so bad but I'm getting so sick of feeling like this all the time..

Is it worth it to keep trying it's been 4 years and I'm only 23. My husband is 29 and I so badly want to bless him with children..he tells me it will happen but I'm losing hope..can anyone tell me how they get thru a bad day??
