Even if they are Bipolar and on a little buzzy track right now all you might really want to do is just be around, be their friend. Some people have full blown in the hospital episodes and still can't handle the word Bipolar. I don't think it is a bad thing that you opened it up. It is better coming from you than from someone not Bipolar. You opened that line of communication. Now back off in order to keep them from ceasing to be open to you. That's my 15 cents anyway.
