It's hard to say what is healthy, because healthy isn't necessarily universal.
But I think anyone has the potential to find a healthy relationship that suits his or her needs.
I'm sure that someone will come along for you eventually. The waiting game is always hard, but I think it's worth it.
No. I've tried. Real relationships don't exist, in the end you are only with someone for what they can do for you, NOT for what you can do for them.
Would you be willing to stay with someone while they have cancer? When they're poor? When they have trouble with alcohol?
If you say yes, how long will you be able to until someone else enters your life? It can't be done. Life is just a series of moments to moments, instead of seeing a relationship as a "Forever" thing like some deluded schoolgirl's fantasy, see it for what it is.. A temporary reprieve from the despair of impending death.
