Well any kind of serious lifelong illness or disability (mental or physical) would definitely make me proceed with caution. I'm pretty sure I'd have it in me to be the friend who stuck by a friend through such junk even to the point of putting dating anyone else on hold (just because I'm like that), but that doesn't mean I'd date them.
A more complete answer would probably involve me asking questions like why would I date or marry someone in the first place; what is the purpose of getting married; how do I determine when I'm loving with the love of God and when I'm trying to be the savior for someone who is hurting, what is the difference between dating and devoted friendship anyway, etc. and that would take several months or years or possibly decades.
