You have some amazing goals to work towards! I know if you put your mind to it you can succeed in anything! Remember, your sisters are always here for support! Some things to look into might be how flexible is the distance learning regarding time to complete course work/take tests and complete the program. Some programs I've looked into are extremely flexible and let you do everything at your own pace and others have lots of extremely strict deadlines and requirements. Each school and program is different just ask all the questions you can so that you'll be as informed as possible about what you're getting yourself into!
GOOD LUCK!!!
You'll do GREAT!
