I know my chapter has gone through cycles of apathy and believe me, it is difficult not to get sucked in, much less weather the rough times. My advice to you is take the initiative (if remaining greek if your decision) and organize some group activities that will promote sisterhood bonding. It will not happen overnight, but with time and patience, you should see a change in the morale. The most important thing is to remain positive. I know it is ESPECIALLY difficult to remain positive when your big sister isnt talking to you...a girl in my chapter had this same exact scenario happen to her and as a result, she withdrew a bit from the whole PiPhi scene...but it has gotten better for her, her big sis has graduated, and there were many other sisters for her to rely upon while all the drama w/ her big was happening. The point is: dont give up. Try and strengthen the friendships you have and focus more on the positive and less of bonding w. your sisters through your common frustration with the organization at large...that will only perpetuate the cycle of negativity and you run the risk of girls deactivating. Try and see what you initially saw in your GLO and get excited about it once more. I had some low points, some times where I questioned whether it was worth it for me to stay in....I am so glad I decided to work through the hard times and stay true to my pledge.
Chin up, babe....it should get better
