I agree with hairball. I'm bipolar and my bf has stuck with me through the darkest depression to dangerous highs and two trips to IP. He's been there and supportive every step of the way. And if someone did leave me for being down, I'd never want them back in my life because eventually you're going to get sad or depressed again and then what? I know you miss him and it takes time. But you deserve someone that's supportive and loves you no matter what.
