I give up

I give up, I have begged and pleaded with God, said miracle prayers done everything, I have ate right, I have taken the steps got myself checked out and my husband, told he was fine and iv got diagnosed with unexplained infertility. Iv tried coming up 3 years, convincing myself that this time it has worked, I feel different, period a day late, bought hundreds of pounds of pregnancy tests and every single one of them negative. The guilt of this burden of not giving my husband a baby, the questions asked all the time when are you gonna start a family? Your near 35 u wld need to start, 20 times a day working in a hairdressers and the same fucking replies, pretending I'm fine and laughing it off. I feel cursed, my whole life seems to be crashing around me. And I feel alone. I give up completely. I cant do this anymore. The anxiety is crushing, the knot in my stomach is the only thing I feel. I'm sick of seeing and hearing other people's announcements, I'm sick of buying baby clothes for other people. I'm sick of people saying when u stop trying itl happen. Fuck it
