Ahh I don't buy the " smarter people" are going to be more accepting. People from any walk of life is someone who might judge you and might now. I think it depends on who ever than person is and how they are in your life.
The Bipolar illness is unique to everyone. People with out Bipolar can try to understand what your Bipolar is like.
There are people all around this world that are going to look down on anyone for every and any reason, not just Mental Illness.
Just do what you need to do to learn how you can make life easier for you. I personally have had to end relationships with some people because they were just toxic to me and my life.
Keep living your life
