Scared

I know this is kinda off topic but in a slim degree it is related to being banded. I have been wanting to go back to college and have recently i had started the process of going back. Well tomorrow I am suposed go take the placement test and i am scared to death. When I went to my psyc eval The guy asked me if i have any other big things that will be happening this year and I told him that besides the band that I had a job promotion but that i wouldnt be starting that till after I return from medical leave, and then of course there was the school thing. Well he told me " dont be suprised if the school thing doesnt happen. because you dont want to get too much on your plate". I think him saying that has caused me to doubt myself and the choice to go back to school. i know that i am going to be taking on a lot between work, the band and school but i dont think i would be over doing it. i am not planing to take a full course load just one or two classes a semester. I can not help but be scared.
