Insurance advice much appreciated!

On Sunday last week I had an accident, lady in front of me indicated left and veered left in order to pull into a lay-by. I moved to the right side of our lane in order to overtake and she turned right last minute cutting into my path.

I managed to slow down enough so that the damage to her car is not terrible, small dent where my tyre made contact, possibly breaking seal, plus some scratches. My insurance company are saying my bike is a total loss, waiting on the third party to inspect. Thankfully I walked away from this.

However, I am worried that she will not admit she was at wrong. Unfortunately there was no witnesses and its my word against hers.

Any advice?

Thank you!
