Given the length of time you've had this and numerous normal exams it's not likely serious. Floaters are normal for some 33 year olds, looking up at the blue sky just makes them more visible, I've had floaters since I was 10 years old. Your complaints suggest you may have a high anxiety level and/or depression. If that is the case see a good psychiatrist for treatment. If you have been to a good Eye MD ophthalmologist and nothing found you should stop worrying unless something new develops or your present symptoms get worse.
