Tbh, I find biology extremely boring, and have actually asked for people to end my suffering. I've also fallen asleep, front row centre, in the middle of the lesson... I also find chemistry extremely interesting. However, I'm plumping for a biology based degree at uni, because it's something in particular that fascinates me. (Virology and Immunology) It has enough chemistry to slake my thirst for it, and is also the best part of biology.
All I'm saying is, look at the other areas of biology, outside your particular course, before you rule it out completely.
