Relax stringyeye. I had big black things after my 3rd FOV and all went away in 2 - 3 weeks so I'm sure that your vision will clear by then. Give it some time. You didn't make a mistake as you don't have collagen floaters anymore since all you see is round and free floating so as the eye fluid replenish itself that will be filtered. The eye fluid is fully renotaved in 3 weeks. I know and understand how you feel but I can assure you that things will be better :)
