Well, if you could walk before you picked up running again but can't after, I think that is a pretty clear cut problem.

Use trails. I've had 4 incidents with cars within the past 3 months and none were fun times and just last week programmed my lawyers phone number into my cell as I might need it fairly soon. If you do not know the cycling laws where you are and are uncomfortable with the amount of traffic, certainly stick to the trails. Besides, trails have all the hills whereas in comparison, roads are mostly flat.
