Serbian/Croatian churches have proven to be places where the Serbian/Croatian
immigrant population in the US meets and keeps in touch with everybody
else, kind
of a community center.
You might be able to find a support group there, even if you are not
particularly
seeking religious guidence.
Also, look around on the Internet. Virtual x-Yugo communities are very strong
on-line, if it is appropriate in your case. Check out http://www.yuqwest.org
for example.
Hope this helps.
