of course there is hope. my boyfriend was diagnosed with bipolar (and i have anxiety problems) so sometimes together we are nuts! but i think the key to maintaining the relationship is understanding...if you have an understanding partner who has taken the time to understand bipolar disorder and realize that the moods are not because of you and that you understand why they are happening, i think you stand a good chance. i have educated myself alot about bipolar and asked a zillion questions to him and learned to understand his moods. and i think all it takes is alot of patience and the knowledge that no one is perfect, we all have our things, and once you realize that, you will find the good in everyone. good luck to everyone
