Cara,
Don't doubt yourself in your ability to do the job because you can do anything you set your mind to the cerebral palsy doesn't define you. You define your life. I am business management major going for my bachelors and I have the same condition and I haven't let it stop me even through people have looked at me different sometimes. If they don't take you seriously its their lost in you planning their wedding.I wish you the best in your studies and future.
