Are you glad you were adopted??

This is a hard question to ask and im sorry if I offend anyone some how, my husband and I are in a situation where we want to foster then adopt and help my husbands 2 siblings we recently come in contact with, the grandpa has custody over then since the grandma died in Jan 2020, we have a child of our own and are in our early 20's, on the inside we feel like we want to do this but we are scared it could be the wrong decision. Has anyone ever went through something like this, and how did it turn out?? ❤
