Eyes Causing Serious Problems

The vision in my left eye started to get blurry and return to normal when I was about 14. Now I am 20 and my left eye is completely blurry while my right eyes sees fairly well. Both of my eyes see halos and starbursts at night when I look at mostly small lights. This causes headaches, and cofusion when trying to read things. Lately im also having trouble doing simple things without getting confused. I feel like im in a dream constantly. Im finding that im losing my appetite and get tired much easier as well. To me this sounds like im dying, but im hoping that somebody can tell me a simple solution to this problem. I have an appointment for the opthamologist, but that is in two weeks and this is killing me so im looking for answers. I tried starting school, but I couldnt think straight and pay attention in class.
