MTSUGirl, keep your head up! It sounds like you are very determined, which is so awesome! And it can be rough to hear things like "but you're a junior!" I heard that junior thing too from my friends when I told them I wanted to try informal recruitment, and it's just like you said, it's a lifelong committment, not just x-amount of years. Even though I still have a ways to go for graduation, I fully intend to become an active alumnae member after I graduate.
It can definately be hard when the people around you don't understand or support you, but you know you have all the support in the world here on GC ! So keep smilling girl!
