sorry to hear about your back pain... vehicles like cars can represent people and their "ministry" either religious or their philosophical crusade. The fact you got ran over by one may point to a time in your past when you got "ran over" by someone, possibly in the church. our back is what we carry our burdens and loads on. Back problems can mean we are carrying too many burdens on our own. Based on your post, it seems you have a lot going on and that can lead to a lot of stress and pressure. I hope you have someone to help you and lean on to lighten your load. It may be helpful to restore some relationships that were burned in the past and let yourself be restored into community. All the best!
