A few questions about the voices: are they simply the voices of your conscious or are they separate entities? if the latter, do they tell you what to do?

I personally don't care for the use of the word 'crazy'. It is sadly belittling. Whoever has given you this impression I agree is hurtful and ignorant. Not exactly supportive.

Talk to your doctor about this. If s/he is concerned enough, they will get a referral to a psychiatrist. Don't allow yourself to be hindered by the 'crazy' word. Consider it as a favour to yourself.
