Does vision get worse due to electronics?

I'm a tenth grader (girl) in high school. I got glasses in 8th grade and I just needed it to see the board. but each year it has been getting worse. Last year was fine, I just needed it for the board, but this year it completely changed. People from short distances are now blurry, I can't see anything on the board, it just got so much worse. And here are my reasons as to why: i've been using a laptop every single day in school for all my classes except math. I use my phone a lot. I never really take breaks from looking at my laptop. My brother has contacts but like i dont know why its getting worse. Is my retina being damaged due to my laptop? I get extremely stressed out due to school work and homework so is that why it got worse? Does it get better as I grow older? And yes I am going to an eye doctor soon but I just wanted to see what you guys think from hearing this. Thanks.
