Trying to keep up the momentum in college + temporary setback

I’m really proud of myself because so far this semester, I’ve managed to keep up with deadlines without having to request extensions, and haven’t turned in anything late. I have accommodations that allow me to have flexibility with deadlines, but I’ve been trying to manage my ADHD so I don’t have to always request an extension for assignments. However, I found myself today having to request an extension for a paper that’s due this week. This morning I realized that I actually lost my laptop charger (left it at school) 😭 so I can’t finish the essay that is due soon. I’ve been doing a better job with having systems to not constantly be losing things, but it still happens every so often, so now I have to buy a replacement charger, which will take time to come. It makes me feel a bit sad because I feel like I’m breaking the momentum that I’ve had with not turning in things late, but I’m trying to give myself some grace because that’s what the accommodations are there for. Do you guys have any tips for managing long-term assignments (like papers, essays, etc.) so you can stay on track without falling behind? And also tips for not misplacing things would also be great 😅
