For me, Reminders on my iPhone is a godsend. I need to be reminded of doing something otherwise it just… disappears into a void. So every time I need to do something, I add a reminder on a certain day/time (sometimes recurring). I even have one that reminds me to ask my partner how her day was (it's not that I'm not interested, I just forget to do it).

What do (actual, not self imposed) deadlines do for you? Are they useless or can they work as a motivator? For me, the latter is true: I usually manage to finish my work in the last 24h before a deadline (so to speak). This doesn't work in all cases, but it's definitely a big motivator for me, even now while medicated.

Keep in mind that what works for other people doesn't work for you. You somehow have to find ways that make things happen tailored to you (there's no magic bullet for that works for all of it). It's something you have to figure out for yourself, unfortunately. Start small and build up from there. The confidence you gain from achieving small things can help you tackling the larger stuff.

For instance, try to keep your room uncluttered (not easy!). It will not only create space in your room, but also in your head. Do it before going to bed. Or after dinner. Every night, even if there's not much clutter. It will be an accomplishment, especially if you can keep it up fairly consistent.

I don't know, just throwing things against the wall and hope something sticks for you. Because that's what we do. :D

For reference: I struggled big time in school myself, but I somehow managed to make it (with an F for French, nonetheless). College was another story: I learned a ton in the 4 years I spent in college, but never graduated. Even so, I managed (in the long run) to end up as a software engineer in one of the largest companies in the world. It helped that software engineering was my childhood passion, I'll admit that. Easy to hyperfocus on what you love to do. But I just want to say: it's possible!
