I have an a in the class and a zero ruins me im trying to get into medical school. My grandfather passed away this summer. My parents are having marriage problems. My grandma just had surgery for cancer.Ik how lucky i am and am waiting for all these negatives to stop. It just seems like everything isnt meant to be. I dont know what to do or how to handle this anymore. You cant make up how this happens. I just wnat to graduate college and my family to be happy and healthy no one else has it this hard.
