Don't know what to do...

Hey guys I'm new to this glow thing but I have been ttc for 2 years now. And I get so upset when I see people's babies and my brother n laws babies and I always ask myself why? So we stopped "trying" and still nothing...well me and some of my immediate close family has been dreaming of someone having a boy..I have tried taking vitamins and I've tried pree seed and nothing has worked..anybody have any advice?
