I'm so sorry. I can't imagine your disappointment. Please be kind to yourself right now.
As for adopting, there are many ways to adopt that aren't so expensive. We were well on the path to adopting - even had a home study done - so we learned a lot. Adopting out of your local social services agency is often free or nominal in cost. Wile newborns aren't always available, you never know, and you may find an older child you would fall in love with. Here in MA if you adopt out of children's services that child gets free tuition at a state college.
International adoptions can be cheaper than domestic, even w travel costs. Especially if you adopt from a place that has great need. When we were looking, adoptions from Ethiopia and some other African countries were heavily subsidized, so the cost was well under $10,000 and the kids could be escorted here so no additional travel costs.
Or if you opt for a private adoption, though expensive, it really isn't much more expensive than IVF if you don't have insurance coverage.
The adoption process can be overwhelming, so look for any resources you can find to help you navigate the system.
I hope you find a path to parenthood soon.
