@Tahli, everyone has a breaking point hon. And God knows you've thrown everything you could have at this. For me I know the end of my journey will come down to money, but there are many other reasons for stepping back that are just as valid, if not more.
You are Momma to a lovely little boy and as much as I know you long for a second child, I also understand that being there, and being healthy enough, to care for him must be your number one priority. Maybe putting your health first, and taking a step back to evaluate would do you the world of good.
You may choose to continue on with IVF in the future. You may choose not to. Either way, I am in awe of everything you have been through so far on this journey, and we support your decision no matter how you decide to move forward from here.
And chick, whatever happens from here on in - please keep popping back in so we know you're ok. You're just freakin' awesome and the place just wouldn't be the same without you
