Medication to ease your through the next 2 years! It takes time and energy to learn to relax as well as finding time to practice. Been there etc. (not the divorce but other stuff) ...... some ADs help anxiety, Betablockas can be useful, Rescue Remedy helps some people, or an 'as necessary' drug to take when anxiety takes over.
Sorry to hear that your marriage hasn't worked. Always difficult, one has to mourn what was, what might have been - counselling might help too.
