Wow...
Your question takes me back about 20 years, when I asked the very same thing, though I was barely able to get the words out between giant sobs. I didn't get a satisfactory answer when I asked, and maybe what I have to say won't be of any use to you, but I'll say it anyway.
Do not presume to reject yourself on behalf of others. By doing so, you've never given them (or yourself) a chance to see if there might be a special connection there.
You are not your disease. You are a human being, and like any human being, there are things a person will love about you, things that are worth sharing with others. Focus on that.
When we look in the mirror, we focus on our own flaws. Don't assume others to, too. Don't constantly try to draw their attention to the things about you that you think of as reasons to reject you.
You are worthy of love as much as anyone else on this planet.
