Low GPA from One Semester- How are my chances?

Hello, I’m here to ask about my GPA. I’m currently at the end of my Junior year of highschooll, recently started applying for college apps. So, in my freshman year, I started off my semester OK with a 3.8, which was lower than I would have liked, but. And then, hell ensued. My depression, anxiety disorder, and ADHD began to manifest in a more prominent manner than EVER. I ended up doing terribly and managed to drop my GPA to a whopping 2.8. And that was after I got all A’s and one B on my finals. I got on pills for these issues during my freshman-sophmore summer, which helped immensely. So I ended up pretty much spending an excessive amount of time doing homework and nothing else. I’ve taken up to Spanish 4 at this point, so I’ll be getting an Honor Cord for that. I’ve also taken four AP classes and am in a math and science program that it about as intensive as AP classes every year. So, in the last four semesters, I’ve managed to get 3 3.9-3.95’s, and one 4.08. This brought my GPA to a 3.78. My SAT scores came back, and I’m in the 98th percentile. I’m incredibly disappointed that my GPA is so low do to one semester of high school. I wasn’t even sure what kind of colleges to apply to. I’ve been on the swim team, I’ve won multiple speech contests, I’ve been in 7 clubs, 4 of which I’ve been in for three years. I’m not really sure what else I could do at this point. I’m still struggling immensely with the previously mentioned disorders, and I’m afraid that I’m going to experience the worst of Senoiritus and I’ll ruin my GPA. My top school that I really want to get into was either Michigan State or University of Michigan, which I applied for a few weeks ago. I’m just so stressed out at this point. I guess I just want to know what you guys think, or if anyone else is in my situation.
