I think I am going to become blind

Hi everyone, I am 18M and I’m really scared right now. I feel like I might be going blind and I don't know what to do. ​I am a wheelchair user, so I can't go to the doctor on my own, and I'm afraid to tell my parents because they will scold me for my high screen time (10+ hours a day). ​Here are my symptoms: ​Blurry Vision: I think I've had myopia for a year, but I don't have glasses and have never worn them. ​Floaters: I see floaters constantly in my right eye. ​Strain: My eyes always feel heavy and strained. ​Watering: My eyes water when I try to sleep. ​Redness: The inner corner of my eye (caruncle) has been red for months. ​White Dots: One time, I suddenly saw white dots like things coming in my right eye. It lasted for a minute and went away, and this never happened again. but it really scared me. ​Is this a sign that I am going blind? I know I need a check-up, but I am terrified of my parents' reaction. Any advice would be appreciated. I am really scared about my eyes right now
