Finding the right person is never easy for anyone but especialy difficult for people with any sort of special problems.
I imagine disabled people, for example, often feel worthless. I know that many feel incredably lonely and isolated. I know an obese woman, for example, who has a lovely soul, but has become hard and bitter by so many years of being ignored, sneared at and suffering abuse from complete strangers in the street.
Janet raises the issue of when to tell. You'll have to eventually.
Personally, I would take the position that people who are so shallow that they set their sights on a fixed level, are best avoided anyway. No-one can ever live up to that.
At the end of the day, you must beleve in yourself and who you are. When life kicks you down, it's because, that's life.
But you deserve to be here and you have something to give back.
