Difficult.
If it causes problem with work and socially, it is better to be open.
I would and did not realise, and worked hard, but successfully, to cope.
Nothing of the disorder has been apparent to others. Nothing to explain.
Now, i am on mood stabilizer, appear the same, but have so much more energy, Why bother. I have told a few, but it did not matter.
Besides now I do not feel bipolar anymore.
That is a good option
