I am going through a stressful time at the moment. It is about an event that happened nearly two years ago where I was accused of hitting someones car which I did not. This person has given me a threatening letter, taken it to the insurance, tried to take me to court and is now taking my insurance company to court. I'm assuming whatever decision was made the other party did not approve of, I do not know what this decision was as I was never informed. I have thought this whole nightmare was over time and time again but every time I just start to feel better it rears up again as I received a witness summons for May during university times. I'm an extremely nervous person, absolutely cannot speak in front of crowds and am terrified. I cannot see any way this could end well for me and fear they're have only sent this me to try and get me in trouble with the law and ruin my life. I have no idea what damage was caused to the other parties car, I do have a witness who saw me not hit another car but my car was pretty damaged as I had hit a tree which my witness saw and I have pictures of the tree missing its bark. I just don't know what to do, I'm terrified and it is all that I can think about. It was so long ago that I do not remember it that clearly but I do remember not knowing that I had actually hit the tree until I turned and saw it right behind my head (I reversed into it and it hit the drivers back bumper and side). And now I'm panicking because I didn't feel my car going into the tree.What should I do?
