Hi Dave I wish I was still living in the UK I lived over there for a bit on a working visa . I would have been more then happy to help you out and chat.
Youre not alone floaters severely effect many I've had them 6 years and I've fallen right back into the ditch of hopelessness I was in when I first had them which is strange because I did overcome them for quite a while.
The doctors are still very dismissive and put you through the third degree... This can make you more dpressed if you want surgery as a last option.
I'll msg u my facebook if you are ever interested in chatting
Stay strong !
