Will I lose my vision because of sleeping with contact lenses in my eyes?

Hi,

I had bad contact care habits as a kid and slept in them through my high school years. And people told me not to, and being naive, I did not listen. Thinking the consequences would just skip out on me. Well, now, years later, I am dismissed from high school, and my eyes are now suffering the awaited consequences. The first and potentially most severe symptom is eye floaters. I see many of them, more than I should be, and they favor my left eye. After one second, they are not there, then I look around, and there are so many of them. The second symptom is my photosensitivity. It is like I see this little orb as I look down at the light, which is just not good. I know it is not. I do not want to go blind, and I am scared. I just want to know if there is something I can do to help my eyes heal or what I should do?
