<human>: Can you give me the gist of the text in a nutshell?

Hey /r/advice, first a little backstory. I am a 15 year old male, a sophomore in high school. About a year and a half ago, my father passed away very unexpectedly. We were pretty close and it was a huge shock to my system. I was mostly fine up until about 6 or 7 months ago. Ever since middle school my grades were all 85-90, but that changed when depression really started to kick in. I started to get insomnia, which led to me being late to school, which led to me coming in at lunch most days, which eventually led to me missing multiple days a week, on some weeks. I really really hate being late for school. I honestly wish that I could make it every day. So the missed school is making my grades really shitty. I only failed one class last quarter, which I have never done before, and as of right now, I am failing every class except for one, but I am on track to passing both of them. Do I need to be worried about the future? I think I am going to make it out of the grade, but I'm worried about college. Do they care much about sophomore year? I tell myself I'm going to try as hard as possible next year, so hopefully that works out.
Thank you guys in advance, and any advice is greatly appreciated. <3
<bot>: Grades sophomore year are declining. Do colleges really look at that? If I get 90's junior year, and good SAT/ACT scores, will good colleges still look at me?
