You'll be fine no matter what you do. Just change your attitude about what you think you are capable of and focus on what you have done that relates to what you want to do professionally and you'll be set. I think your mind will be as pliable if not more than the people you will probably have to work with. Use that pliability to your advantage. People that are complacent in a particular domain of problems are really at a disadvantage in the long-term when it comes to software in my opinion.
