Speaking as a SisterFriend who has been in similar shoes....
Gamma, friends are friends.
Friends are
going to stick by your side. Period.
I assure you that, if anyone even cares, when people start 'speculating' -- if you ignore it and continue being as earnest and sweet as you sound in your message... EVERYTHING will pan out.
Remember I am speaking in the tone of someone who's felt the same way... and now I've found that the few gossipers that cared lost their power when I continued my friendships with former SFs (now Members) as they were... FRIENDSHIPS.
Don't give a shadow of a an assumed speculation power over any part of your life. You are stronger, smarter, and sweeter than that... right?
You are stressin'

Chill...
Focus...

You've got a whole lotta work before you, and you are going to need your good friends around for moral support... not just for help with your pursuit of Alpha Kappa Alpha Sorority, Incorporated.
So continue, strive, work hard, do well... No need to feel weird.
(and i admire you for having/maintaining high standards for yourself, i.e. your grades. Yougoguuurrrl!!)
Peace
