About a year ago I witnessed a crash. The driver was ok and shaken and I had to pull her out of her upside down car. The accident was caused by a lorry going around the outside lane around a roundabout and just tipped the back of her car. The ralisation of how little a force a lorry has to touch a car to flip it and noticing many mistakes by lorry drivers has made me petrified of them. I will drive but panic passing lorries so follow slow behind. If im a passanger and we pass a lorry I close my eyes and grip the seat belt. It is getting worse and worse and I am worried ill be like my mil qho wont drive on motorways and only routes she knows well. I was a confident driver before. Not overly to the point of being dangerour but I feel so uptight I feel dangerous. Any suggestions?
