I'm in the same position WeV, just started to get back into running after 18 months of zero motivation following a period of depression. A few things have helped me get back:
1. find a friend to run with, someone who is close to your pace or who has signed up to the same event as you.
2. Don't be too hard on yourself - start with running once or twice a week, then build up to your old schedule.
3. Sign up for a few shorter events building up to your marathon, then it won't seem like such a big mountain to climb.
4. Try and mix one or two other activities in with your running - something you could continue if the worst happens and you get injured :-/
Good luck, and stop being so hard on yourself... one day at a time
