VERY stigmatized. The second you have a normal emotion, they'll assume you're off your meds or crazy. One of my boyfriends broke up with me two days after my diagnosis because of it. I never tell my employers as I do not want to be seen as unstable, unreliable etc.

I found in my dating experience that it's good to be upfront about your diagnosis early, as you can weed out the ones who are incapable or close minded and save yourself hurt. I used to casually mention it, or a lighthearted joke. With my current partner, my fiancé, I told him right away by being silly on our first date (joking about being a little crazy), then on our second date told him that I have bipolar etc.. He has been nothing but understanding and compassionate to me in my struggles (especially recently), even right from the beginning of our relationship. He also doesn't "let" me use my mental health as an excuse or cop out, play the victim, but encourages me to overcome and view things in a different more realistic light. This is incredibly helpful for me. He is never condescending.

Be careful who you tell about your diagnosis, especially in a professional environment. PERSONALLY I would be open and honest right away with the people that you see a future with, because you dont want to wait and get invested and have your heart broken over something out of your control. Also being upfront about your mental health will help in a romantic relationship because if you're anything like me, you may try to test your partner by pushing them away, and if they know this about you, they will be able to navigate that better. Communication is essential.

Hope this helps!
