Maybe instead of searching for a perfect timetable, try just writing one up in Word using a timetable template. I always found that the more I tried to perfect my timetable, the less likely I would be to stick with it. If you look around at the other threads on this kind of topic you'll see that everyone has different forms of organising their time.
You still have a few months to find what works for you so try a few different methods. Maybe for a week just keep a to-do list and see if you can complete that every day. Then the next week try a strict schedule, etcetera.
Instead of focussing on a perfectly aesthetically glorious timetable, just look for what works for you.
