Places to avoid would be Oxford, Cambridge, Birmingham, Edinburgh, Bristol, Cardiff, East Anglia, KCL and Hull York. I'd say avoid Leeds/Leicester too since GCSEs are a significant part of their scoring systems and they were very competitive this year.
I've got a similar GCSE profile to you and I managed 3 interviews and an offer, so all hope is definitely not lost. Just practice well for the UKCAT, write a decent PS and apply smart.
