I haven't applied anywhere yet, feeling utterly hopeless

I have barely applied anywhere yet except one safety which I don’t even want to go to. I have no essays, no rec letters. I had bad mental health early on in the school year, and I’m like 100% convinced I have undiagnosed ADHD which contributed to my procrastination, though I’m aware these aren’t excuses.

I’m not even a bad student, I have a 3.7/3.87 UW/W GPA, a 1320 SAT (1350 if I super score) so I feel even worse knowing I actually had a decent chance had I actually tried. I know I can still do regular decision, but realistically how good would my apps even be in such a short time? People literally start this process months in before and I feel like such a failure not having done anything.

I tried talking to my parents to see if I can take a gap year to become sure about what I want to study before applying again but they’re completely against the idea of it. If anyone has previously been in this situation or just generally has any advice on what to do I’d really appreciate it. And please don’t tell me things like “you did this to yourself” I’m aware of how fucked I am. :(
