I got into my dream program as well, but I do wonder if I've made the wrong choice. I chose an unfunded offer, and I have very little money. Sometimes I'm sick with worry about if actually being able to do it. It might not have been the wisest decision, but even if it's difficult, I know I won't have any regrets down the road for not taking the chance. I think it's natural to worry, but you just have to go with it, and not think too much about the "what ifs."
