why leave?
leave yourself a way back in. you can go on vacation from toriabsh for like couple of weeks/months. i you feel no pangs of regret, come back one last time and sell you account (ddunno why u'd do that, i think its pretty retarded)
get yourslef some new friends, hangout in differnt places then before.
my clan blown up too, 2 of my friends who were imporatna clan members, and one of them a clan moderator, left clan. i left too, and now the remaining clan leader hates my skin. trust me, the feeling passes.
