I am not in the field you appeal to for answers but I have gone through some similar situations.
I tried photography as a career path and felt much as you did in the photo lab. There are however, many pro photographers who just do the shooting and give the pics to their lab technicians for touch ups, etc.
When I took college biology, I had a bad time in the lab because the TA was a psycho. There are many unsavory aspects of university life, so you might find a workaround. It's possible to take the lab after taking the theoretical course at the same level and perhaps at a different institution.
The "lab" is the basic data generating point for many fields. My opinion is that, if you don't like the lab, you don't like the field, although it might take some years of experience in a field to realize this. In the days of film photography, a photography who did not do his own lab work would never get exactly what he wanted. On the other hand, a math professor of mine once said that in computer work, the further away you were from a computer the more money you made. So I am wondering if mathematics might be a better fit, unless there is a special reason you are drawn to chemistry or engineering, which also has a strong lab component.
