My mother knows. She doesn't fully understand, but she is coming around. My brother has MH issues also, so I shared my diagnosis with my brother (plus he was well aware that I was having a lot of problems growing up, but now he knows specifically).

I mentioned my diagnosis to my cousin, who probably doesn't even remember me bringing it up, because I don't talk about it much. Plus, she has her own issues with addictions and was even diagnosed as Bipolar. I only talk vaguely about my mental health issues with very few friends and not all of them know my diagnosis.

My one friend knows my diagnosis, and I mentioned it at one point to another friend. But I could probably count on less than one hand the people outside of family and medical professionals that know.

I have mentioned it to past partners, and most were supportive. However, the last guy that I dated for only a very brief period of time was pushy about getting off medication. He seems to think cannabis is the answer to everything, which is why he is anti-medication. Needless to say, it rubbed me the wrong way, and that was one of the many reasons why I ended it. Now, I decided I won't open up about it once I've been in a relationship as soon as I did before.
