I know what its like. I am ADD combined type but most people only get a vague notion of me being 'different' but they can never pin it down unless they are neurodiverse themselves.

Every day feels like its three days to a normal person. Nobody suspects that everything is so much harder for me, not even those who I have told about it. Its the same with your bipolar, if they can't see it from the outside its not there to them.

I take it your father is a Sensor type person? That is the kind of reaction to be expected.
