My family knows about my bipolar disorder, but my friends and acquaintances do not.

This is a personal decision and it's completely up to you whether or not you want to share this information with others outside of your family.

If you're considering telling your friends or acquaintances, here are a few things to think about:

1. Comfort Level: Are you comfortable discussing your mental health with them? It's important that you feel safe and supported when sharing personal information.

2. Trust: Do you trust these individuals to be understanding and respectful? Sharing sensitive information requires a level of trust in the other person.

3. Support System: Having more people aware of your condition can sometimes help build a stronger support system around you, but it’s also okay if you prefer keeping it private.

4. Education: Be prepared for questions or misunderstandings. Some people might not know much about bipolar disorder, so being ready to explain or provide resources can be helpful.

5. Impact on Relationships: Consider how this information might affect your relationships positively or negatively.

Ultimately, the choice is yours and should be based on what feels right for you at this time in your life.
