Oh, Tilly, I am so sorry to hear of your challenges. Of course, it is your decision, but I hate the idea of you going back on any drug. One of the things I had to use for bills was an envelope with a schedule of what to pay and when to pay it on the front where I could see it, boxes for each month of the year. When I got a bill, I'd put it in the envelope (one of those large ones, the bills can fall out of folders) and when I paid it, I checked off the box for that bill and the month I paid. That helped immensely.
As for being proactive, a Franklin planner helped me tremendously. It takes time to set up, but once you do, when you recognize an issue, they have a system for you to write it down and take action - very helpful for staying on target.
If you are not able to do that, for me, just having a small spiral notebook where I wrote down issues sometimes helps, if you can also set aside a daily or weekly time to review issues and track your progress towards dealing with them.
Grammar, spelling (use a word processor), politics and world issues, I know they are good thermometers of your capability, but right now you need your resources to deal with transition. If you need to take some energy away from these other things for a time to deal with the transition, that is fine. If, after the transition, you still have trouble in these areas, then you can look into strengthening them again.
Not legal or professional advice, just related to my experiences. Bless you.
