I graduated from a magnet high school, almost done with my BS Chemistry, and preparing for pharmacy school, but I'm getting tired of school. I'm too pressured from my classes to remember everything or be interested in what I'm learning. I feel like my life would be just fine if I worked in retail, restaurant, or just a technician. Is this feeling normal?
