The person who is crazy and does not know or want to admit it, is crazy. The person who is crazy and admits it and seeks professional help, is really not that crazy after all.
I agree with all of that but would like to add my perspective because I live with someone diagnosed with BiPolar disorder.
When a med adjustment is needed, the person who is crazy and seeks help might still be pretty crazy (occasionally) but the person who is crazy and doesn't want to admit it or get help is crazy all the time!
