Twinkle yes, fortunately for me and DH, we were. Our infertility is male factor (DH low sperm count, almost low enough to be considered zero, medically speaking). I, as far as we know, have no issues apart from my age - which wasn't an problem when we cycled but would be now.
I was on another, fertility specific forum at the time and cycled with 9 other women who all needed ICSI due to male factor. 5 of us were successful, 5 were not. It's such a bitterly random thing. I saw how devastating it was for the unlucky ones and talked to them at length. I can't tell you how gutted I am for you having had some insight into what it is like.
I put on 10lb during treatment alone, and I hated it. It was so hard, both mentally and physically. It's one of the many reasons DD is and will remain an only child.
