Eye floaters

I have no idea if this is the proper forum for this.
I'm 18, female, and I have a bunch of floaters.
I have visual snow ontop of it, and I've always been a worry wart.
I've been to the eye doctor, doctor, even a therapist and they can't seem to help me, my brain just won't get over the idea I am going blind.
Now my eyes hurt all day because I think/focus on my eyes all the time, and in truth I can't live like this anymore. I was hesitant to register here but I guess I really don't know where else to turn at this point.

I've been having floaters for the past year or so, I'm 33. I went to an eye doctor and he performed a battery of tests and no major issues. I'm also a worrier but feel better after seeing the eye doctor. When you focus on your eyes, try to focus on something else or seomeone else. Stare at a wall, stare at your hand, really focus on any other object around you.
