18 in May, worries and questions about high myopia.

[Kenan2000]

Greetings everyone, my name is Kenan, in May of this year I'll be 18 years old and i have high myopia (approx -7 both eyes), no one in my family has history of bad vision or myopia.
I study quite a lot and I'm planning to become a business analyst which requires a lot of computer work as well.
My worst fear is becoming completely blind due to RD or degenerative myopia, I'm not sure how to get rid of it, the only things that calm me down are the facts that I'm lucky to have such vision in 2018 considering that medical treatments are improving very quickly, it's just i don't know when exactly when it will stop worsening.
I have nothing against wearing thick glasses or whatever, i just don't wanna loose my vision COMPLETELY as i enjoy reading books, interacting with computers (programming, playing games), etc.Plus I'm still kinda socially awkward, trying to learn social skills, i don't want to end up completely blind...
So my question is do high/severe myopes become completely blind or just live with some problems and burden but that's it?Thanks.If someone can help me to "extinguish" this fear, I'll be really pleased.

If you see an ophthalmologist yearly, live a healthy lifestyle (don't smoke, exercise, eat good diet, etc,) and avoid injury to your eye the chances of you ending up blind in both eyes are extremely small probably 1 in 10,000 if that high.  -7 is not that high.

Thank you for answer, mr John.But in general severely myopic loose vision completely (pitch black, no central, no peripheral vision) or most of the times the worst that can happen to them is legal blindness (at least peripheral vision stays with them no matter how bad)?

We are going around in circles and I don't have time for that.
