Someone that has learned a lot of languages could this be a form of multiple personality disorder?

i have schizophrenia(already diagnosed with a mental illness)but could multiple personality disorder be an addition to it.Because i know a lot of languages from never being linguistically or culturally satisfied.and wanting to know every language that has beauty(i don't plan to mention this concern to my psychiatrist because i like to keep my linguistic abilities to myself and wouldn't want something to sedate me causing me to lose my language learning skills)
