I don't know. I mean, I know I'm sensitive but I guess I just don't really care much if I'm rejected? I don't join groups anymore. I usually just rp with friends, whom are much more accepting, or ask to rp with another character alike mine such as humanoids. Once someone found the rp we were in boring (Likely because it had nothing to do with romance or you know what. BL //sigh//) and deleted me soon after.
They never worded it, but now that I look back on that I even feel a little glad because I don't want to be roleplaying with someone like that... Yes. I have to tell stories now. <3
I am a little nervous sometimes, like if I'm rusty (And that I am. Especially right now.) and kinda like their character... I don't always have a way to make the rp exciting, y'know? Although people are a lot more accepting than I might believe, and me or my rp partner(s) might find a way to making it exciting easier than I think.
Otherwise if they are unaccepting all of a sudden then hey, whatever. ewe' I can see how you'd be hurt by rejection, though, I even have my own story of that but in the end met my own rp group through that. Even I'd be pretty hurt if it were to happen to me today, too, so now I just stick to my group mainly.
Sorry for the ramble. To sum it up, I just stick to my own group now. When I do go outside of that I try not to worry, though, since I'm less anxious than I was a year ago. ^^'
