sisters of mercy lyrics

Can anyone please help me understand the lyrics of “we are the same, susanne”, if you know it. it’s not that I quite don’t understand English but I somehow happen not to be a native speaker and I think I miss something when trying to comprehend the verse:
" give it a name Susanne" , of course in the context.

and what’s “I’m lost for stupid again”?

thanx for all the contributions
