I have schizophrenia and people think I have a multiple personality sometimes... It's not that I have another personality It's just that I repeat what my hallucinations are telling me. If her condition is really bad you need to get some real professional help. Her condition can get worse if you let it go without anyhelp. I don't know much of fetal alcohol syndrome. All I know is that it could've messed up her head as a fetus and now she's getting the reaction from it.
