Right off the bat, I can't really think of anything to say. I don't think fear of rejection is much of a problem for me. Let me think further.
Looking back, I haven't experienced a great deal of rejection in my lifetime. That's probably why I'm not that afraid of it. The number of people who've accepted me has always, by far, outnumbered the number of people who haven't. It's possible that I'm just being too optimistic and naive about that fact, but I don't think so. Even if I was, at least I'm happy with my level of acceptance!
I'm usually pretty open with people right away unless it doesn't make sense to be that way. I speak of myself objectively, so even if I share the most intimate details, it usually doesn't feel personal to me. If it does feel personal, I keep going anyway. I like to be real first - and then deal with the consequences. If I ever do feel a bit of fear, I just become more cautious, but I still stay real and still keep on moving forward. I really can't be that afraid of what one person will think. If I a little timid, the more I share, the better I feel about it, because it's much easier to be rejected because of who I am than it is to be rejected because of a misinterpretation.
I can be sensitive about things, but I usually just deal with those issues if they come up. I either rationalize it in my head and move on or I deal with the matter externally without becoming too moved by it.
I can love all people and be completely open with them, but it may take a year before I actually feel close to them. That's probably just because I'm independent and don't form attachments easily. For romantic relationships, I know who I am and I'm pretty cool with it. If a person left me because of who I am, it wouldn't really change my opinion of myself. I would, however, examine why they left me because I can still always be better. Maybe they've given me a departing gift by telling me something I didn't realize about myself.
However, if there is some more to this fear of rejection stuff within myself, I'd love to discover it. If I'm only fooling myself, or missing something important, that would be cool, because that would mean I have more opportunities hidden away still.
In general, though, I'd say if I ever have fears of rejection, they are smaller than my desire to connect with people, explore new territory, and challenge myself, so the fear never stops me from moving forward.
