Sorry to hear about the accident. Sounds like you are moving toward not driving. What other methods are available. Here we have buses trains cabs Uber.com and local companies that deliver people door to door for work days for a monthly fee.
Clamminess is something I feel when I get over carbed. When I stick to a high protein diet and regularly health snacks every 3 hours I have more control over my emotions and feel better. It is a life style change that may take some time to make a noticeable difference.
Hang in there. You will get through this.
