TITLE: Reddit, I think I've completely screwed up my future
POST: Somewhere right around the beginning of high school I came down with what I can only assume was a pretty major undiagnosed bout of depression. For about 2 years, I was extremely depressed and had no drive or motivation in my classes. This caused my grades to drop dramatically. 

I'm just finishing up my Junior year in high school, and it's time to start looking for colleges. I'm still pretty smart (I'm not just saying that, I got a 2050 on the SAT and 32 on the ACT) but because of those two years, my GPA is a miserable 2.9, my class rank isn't even in the top half, and I have next to no extracurricular activities. Considering I want to major in computer science, I feel pretty screwed when it comes to colleges. 

Has anyone been through something similar or have some advice for me?
TL;DR: 
had no motivation for half of high school, GPA is a 2.9 but I have great test scores. Do I have any chance at getting into a good school and if not, can  I change that?
