I think im getting beyond depressed now, everyone around me are either pregnant or gave birth, friends who married months after me r prego or jsut gave birth, i feel so devestated ive been ttc for 12-13months i know it might not be long for some, but its really affecting me so badly, i feel hopeless, i just dont know anymore i dont kno what to think? Im just isolating myself from the world, i cnt bear hearing anymore baby news. Its getting to me alot :(
