dropping

So I got a bid to sorority I thought I wanted, but I haven't really bonded with anyone in my PC or any older girls beside maybe 1 or 2 that I'm okay friends with. My friends that went into other chapters seem to love where they're at and do a lot more sisterhood activities and older girls seem to actually involve them, and have found a great group of friends. I know it all takes time, and I want to believe that it will get better, but I've been making an effort to get involved and go to meals and meet my PC, and it just isn't working still.

Can I re-rush after initiation, or is that it?
Is it weird to re-rush? Do girls hold it against you?
If I would possibly want to be in a house I preffed this year, will they pref me again, or will having not chosen them the first time have ruined my chances?
Any advice would help
