wish me luck!

I have a (almost) 5 month old son, and I've decided to go back to college. Many are saying "good luck" sarcastically, and saying I won't be able to do it which makes me really want to do it but I'm stressing myself out because 1. I have ADHD, and 2. I have short term memory loss but I graduated from my high school with a 3.6 gpa with cum laude with many people saying I wouldn't be able too with my disabilities. Teachers even went out of their way to tell my mom I wouldn't be able to make it but I did, and that is what's making me go back to college. I'm going back to become a veterinary assistant, and yes I know it's a demanding job but really I'm not only doing it for myself, but also my son. My son was born a preemie who may or may not have learning disabilities like me. If he does have the learning disabilities like me I want him to know his mom didn't give up on her dreams because of her disabilities, and neither should he. I'm mostly stressing because it's a 12 month program. 11 stages. 6 online, and 6 on the job training. I'm mostly stressed because if I only get two retakes for tests throughout the whole 12 month program, and if I fail a test to times or fail two stages I get kicked out of the program permanently... so I'm freaking out about that and the fact that my son is 5 months old and every time I try to sit down and to study he immediately starts screaming for me to hold him, and I can't contentrate. My husband is stationed in Virginia, and our families are 14 or 15 hours away from us, and we have no friends to watch our son even for a few hours while I study so I'll have to study when I can which is starting to be rare when I can be alone and study... so please wish me luck! I need all I can get!
