I am currently re-researching ADHD management (for gods know what time already) after wasting the entirety of the past two days.
Wherever I go, I only see people talking about medication. How good it is, how to approach it, what to expect from it, how it was impossible before meds, how to treat them, etc.
I cannot obtain meds. Stimulants are illegal in my country. Strattera isn't, but I am afraid that I will not be able to pursue diagnosis for reasons I am not going to share here. Please do not tell me how good meds are - there is nothing I can do to have them.
I tried organising my thoughts, having a schedule, and so on (org mode in emacs), but I have forgotten about it, every single time I tried it. I have set up a periodic notification to remind me of it, I quickly started ignoring that.
What can I do to make it better? How can I make sure that I will not just forget to do the things that make it better? How can I make sure that I will not outright ignore the things that help me?
For me, rigid scheduling and body doubling helps the most besides my medication. For studying, using the Pomodoro Method worked wonders and helped me chunk through the material. You're just going to have to try lots of things to see what does and doesn't work for you because it's so different for everyone.
It's going to be very difficult but you can't be the only one in your area going through the same thing. As TerminalEncounter mentioned, CBT should help a lot. You could also reach out to your therapist and ask if there's a group or something for support.
Last but not least, if there's something you remember to do- go do it right away. You'll forget or put it off.
