Hello my friend.
First and foremost, you totally did the right thing. If this gentleman cannot handle your dx it's better to find out now instead of later when your more emotionally invested in this relationship. Continue to be honest, open and give him the time he needs to decide for himself that the tx you're receiving makes a huge difference than someone who won't take their meds. Be patient with him...you can harly blame him for his need to watch your moods...this is a very smart thing for him to do...he'll come to the conclusion that you are NOT crazy and out of control...this will offer him the security and willingness to move forward in this relationship.
I'm very happy for you that you are in a relationship and that your experiencing a connection with a fellow human being. It's fabulous that your willing to share yourself and your feelings with someone. It's never too soon too be honest about who you are, what you bring to the table. A very wise person once told me, We are only as sick as our secrets. Plus you won't feel the burden of keeping a secret, eating a way at you. You're doing just fine.
I know that this is just my opinion, but perhaps you can take some positive encouragement from what I've had to say about this.
You're friend, TgrsPurr, xo.
