Can you adopt with past history of depression?

I don't know about adopting from another country. but I know that with our adoptions it was never an issue. I suffered from major depression when I lost my father, then even more so when dealing with our infertility issues. I am actually on welbuterine. DH has PTSD from being molested as a child as well. We simply got notes from our doctor.I think that depression being as wide spread as it is these days that what the real concerns are is probably bi-polar, schitsophrenia (sp?), and other major diseases effecting the ability to raise a child in a stable environment.
