<s>[INST] By the time I was five, I knew that I wanted to be a doctor. I struggled in school through elementary and middle school, and I never gave up. Once I entered high school I found my niche. I excelled in the sciences, particularly biology and chemistry. I am now in my second year of medical school. I thought that would be enough, but it is not. The second year of medical school is proving to be much more challenging than I thought it would be. 

I have been a student for my entire adult life, and I have had to sacrifice so much in order to pursue my dreams. I have missed out on birthday celebrations, family gatherings, and holidays. I am now starting to doubt whether it was all worth it. I have to question whether it is all worth it. Is it normal to have doubts about becoming a doctor?[/INST]
