it does sound like a psychiatric disorder. but i want you to know nobody controls your mind but yourself. it is yours and yo[u just need to learn how to control it the way you want to. if you have any unwanted thoughts of government control or alternate galexy messages i would suggest you to learn how to realise that you need to ignore them. and think for yourself.
And if you think words will come out a mess and out of order... try to stop and really think about what your trying to say. talk slower so people can understand you and so you can really understand yourself aswell.
also i suggest you to look for professional help, if your questioning it it's always best to try
