I don't think that your values weigh you down, but rather how you weigh them is, but let's start where your unhappiness started:
You said that having trouble moving on from your latest ex. (I'm assuming you're talking of him) You're having trouble understand his reason for breaking up with you. What was his reason for breaking up with you? I don't know. You don't know. However, despite his motive for doing so, the only thing that can be done is accepting the way things have turned out for the time being and moving forward. My friend told it to me in the best way:

we're also solo shows.
we're our own spotlights
we're our own managers
and until we get our gig going
and find someone who shines as bright as us
we're not going for two person shows.
we're going to rock it awesomely... as one person can

But I understand that it's only half the problem.
You talk about you're health, but I think that you're talking about much more than your physical health. You're demoralized, depressed about what people have said and done and anxious about what they'll say and do next, which leads me back to the first point:
I don't think that your values weigh you down, but rather how you weigh them is hurting you considerably. I think that you value your relation with other people; that you value how they see you a lot more than you let on. And all of this leads back to the first post: You say that no one wants you, that everyone points and laughs and whispers about you, but I don't think that's true. I think that you are worth more than you give yourself credit for, that you are, indeed, a lovable person and that you can be "that girl".
