well... believe me, i've been and loads of ppl as well, through ur stage.
so first of all, don't panic. and don't let the others affect ur choices.
here are some personal advice.
first of all, stuff that u learnt in a degree must be sth u reli like.
coz they're reli hard (big gap from A-level, esp. when u're at 2nd yr) and requires loads of enthusiasm and high workload.
so think seriously.
based on wt u've told, i think pharmacy would be much better than pharmacology.
as u haven't decided wt u wanna do, pharmacy sector is quite big for u to choose.
if u work in an industry, u can choose to work in R&D.
or if u want to touch a little business, then u can go for a marketing sector of pharmaceutics or even management.
so basically even if u choose pharmacy, doesn't mean it's unrelated to other things.
i've an option module abt the economics in pharmaceutics, which is quite interesting.
after u've finished a degree and registered, then u can choose whether u wanna continue to study for a deeper pharmacology in PhD or work in industry.
So i do think pharmacy kind of gives quite large flexibility to choose.
hope it helps.
good luck =)
