You're right, variations in your exercise routine will help keep you motivated, so you've really solved that problem yourself!
You will just have to go for your driving test again. The majority of people don't get it right on their first go. Go with a clear mind, listen to your favourite music just beforehand. I did this and I passed!
You started an Aspie group yourself, I really admire that. I feel that it would be a difficult task. After all you've been through, I'm not surprised you're taking a break. And you will still be keeping yourself busy during that break! You have awesome drive and determination, qualities that will get you where you want to be in your life.
All the best to you,
