Can anyone predict the future???

Today, we had introductory classes to orientation and mobility where they teaches how the blind cope with cooking, daily living, going around doing daily chores. Because it was an introductory class, we were asked to introduce ourselves personally. When it comes to my turn, the teacher actually advised that I do not attempt to continue my final semester (semester 8) for my Pharmacy course. I was quite taken aback because so far all the teachers that I’ve met suggest that I continue back after my training. She told about how a student with limited vision lost his/her vision after prolonged use of computer.
I’m in dilemma now... I want to finish the course, but I know finishing the course if not worth it if I lose my eyesight due to it. But job options for visual impairment or blindness are very limited. I can’t do massage due to previous injuries...Another teacher suggested that I take counselling course...I am so lost. I can’t decide what should I do, I always make wrong decisions in my life.
