Don't get too down! I know second year is extremely boring and also pretty hard, but i didn't do a summer placement until end of third year. I applied to late to do a paid summer placement in hospital, so did unpaid work experience stuff for a week. It shows that you are eager and that is the main thing.
My hospital tutor in 3rd/4th year at uni said that when they're looking at applications, they want to make sure that the person understands exactly what they are planning for. Nobody will have extensive experience of hospital - you can't really hold down a hospital job whilst studying, so the emphasis is different to community. I'd recommend getting some experience, even if it is unpaid. Write to your local hospitals pharmacy dept's and explain why you want to work there.
As for community placement, there are usually loads about until fairly late. Boots/lloyds try and pressure people into making decisions in early october, but in reality we were still getting circular emails sent to us in around march/april time begging for people to be pre-regs, usually for independent pharmacys.
As for boots... . Anyone with experience of working for them worked against the company cos everybody seemed to hate them and their strict money-grabbing hand over fist ethos.
Just relax for now and concentrate on having fun in your vast amounjt of free time whilst you still have it!
