Needing surrogate parents as an adult ......?

I'm sure there would be someone in your area, minister of religion or one of the voluntary organizations which abound, to advise you on this. One of them will know some elderly person or persons of good reputation and will know if they would welcome a surrogate family or not. I know for a fact that there are oldies out there who would dearly love to have someone like yourself approach them. I wouldn't do it through any website. Find somebody who knows somebody.
