I don't know how I feel about this overall. On one hand, it is definitely frustrating and aggravating when people think that you're "fine" and that you're either lying or misdiagnosed. On the other hand, appearing "well" is a testament to how well I am able to handle myself around others, and sometimes even a testament to how well I am coping (assuming I'm not hiding anything). So, I see this as both positive and negative at the same time.

Like you, BadNews4321, I know that no one has ill intentions. Thus, I think this time would be a great opportunity to educate people on what's going on. I'm not saying you have to be rude about it, but genuinely explain what's going on and what it's like to cope with bipolar on a daily basis. Explain how far you've come and what you have to do to stay well and cope. Turning these situations into learning opportunities is incredibly powerful for everyone involved. It lets you help others understand you better, and it helps others understand the illness better.
