I hope I don't sound like I'm whining...

so I guess just to give some background I am 25 and married to a and who makes my everyday worth living. we have been together for 6 years now. We have been trying to conceive for over 2 years now. I have been to a fertility doctor. All that really came of that was he told me I was over weight and all I had to do to get pregnant was lose weight. In the last year I have watched soooooo many people I am close to have babies. I have hit a point where I cannot be happy for other people because I am so miserable for me. My mother tells me this isn't healthy and I need help..... I do not know what to think. I just guess I am looking for reassurance that I am not alone in hitting a point where watching others makes me unhappy? Am I crazy? Is this just me? Will my heart ever stop breaking? 💔😓
