Adoption regrets?

Where I live "older parent" adoption from foster care is pretty popular. Heck, older people parenting is on the rise, period. Not to mention grandparent parenting... I've been part of a foster/ foster-adopt support group since 2005. There's a group of older parents who began fostering when their kids were older or in college. Many of them are on their 5th or 7th... adoptions! They're probably in their early 60's now. Caseworkers love them, because they're just incredible parents, they know their limits, and do such a fabulous job with children. One couple takes medically fragile children, she's a nurse: they took a baby boy expected to die soon... he's now about 12 or 13, and *brilliant*. Likely he would've died without them. Another couple just love being parents, both are *so* great with children, the mom especially has the knack, is funny but strict, the kids just love her, always leaning on her. They adopted a 2-year-old at 60-ish, similar scenario as yours. He had become a part of their family, they just couldn't imagine letting him go, worrying if he'd be able to adjust elsewhere or not. Just his anguish at losing them.Me? I'm older, too. I told my friends, "You go take your art classes or travel in Europe, I want have a second family and heal children." It's my choice, it's what I enjoy most, perhaps because it's so complex. My niche is boys with high emotional/psychological damage, healing them is tons of work but so rewarding. RAD, PTSD, etc. I have support from friends with children, I don't parent "alone" tho single. My aunt calls me "her niece with a calling." I think it is a calling for myself and many others.Is it a calling for you? Do you love being parents?
